Item Análise de intervenção da política de garantia de preços mínimos sobre as séries de preços do milho no estado do Mato Grosso de 2009 a 2016(Universidade Federal de Goiás, 2018-02-19) Abreu, Douglas Paranahvba de; Ferreira, Marcelo Dias Paes; http://lattes.cnpq.br/3436824386339415; Wander, Alcido Elenor; http://lattes.cnpq.br/8250997651281553; Wander, Alcido Elenor; Silva, Adriana Ferreira; Figueiredo, Reginaldo SantanaAn important characteristic of agricultural production is the volatility of the prices of its products, caused by excess supply in the harvest period and shortage in the off-season, in addition to other factors intrinsic to the activity. Despite the complexity ofthe real economy, specific methodologies are used to verify the effects of public policies that aim to stabilize agribusiness prices. In Brazil, has been history the Minimum Price Guarantee Policy, which since 1943 aims to guarantee minimum income for rural producers. The objective of this work is to collect specialized literature on the subject and to verify which methodology is most appropriate to measure the effects ofthe PGPM on agricultura 1 prices, then to use the same methodology to verify the effects ofthe PGPM on maize prices in the State of Mato Grosso, which is the largest Brazilian producer of this important grain. The hypothesis is that the PGPM would have positive and significant effects on prices, however, through the identification and use of the most appropriate model presented in the literature, which were the Models of Intervention Analysis in Time Series, the results indicated that Interventions (PGPM) on prices did not represent a positive and significant homogeneous effect, creating evidence that in Mato Grosso, from 2005 to 2016, other market variables explain the price changes in addition to these PGPM instruments.Item Expressão de genes ortólogos relacionados à tolerância à seca em arroz(Universidade Federal de Goiás, 2014-04-04) Abreu, Fernanda Raquel Martins; Brondani, Claudio; http://lattes.cnpq.br/4775600104554147; Brondani, Claudio; Pereira, Maristela; Vianello, Rosana PereiraDrought, a major problem concerning a sustainable rice production in Brazil and worldwide, is responsible for a series of plant responses, including modification in gene expression, accumulation of metabolites and protein synthesis. In order to verify the correspondence between five Arabidopsis genes (PLDα1, LEW2, GluR2, Lsi1 e EIN2), previously related to drought tolerance, and their respective orthologs in rice, the present study analyzed two contrasting rice genotypes for drought, Douradão, the tolerant genotype, and Primavera, the susceptible one. The genotypes were submitted to drought stress and subsequently evaluated for gene expression by quantitative real-time Polymerase Chain Reaction (qPCR). The comparison of gene expression, between leaf and root tissues, showed a greater expression in roots, within their vegetative stage, and leaves, within their reproductive stage. Differential expression were observed mainly among the genes whose orthologs in Arabidopsis encode phospholipase Dα1 (PLDα1) and ethylene-insensitive protein (EIN2); these proteins are directly related to abscisic acid (ABA), a phytohormone that when identified in higher concentration in cells triggers the expression of drought stress-responsive genes, besides it is also responsible for the regulating the water loss (by transpiration) by controlling of stomatal movement. The results suggested that orthologs genes were in fact drought stress-responsive genes in rice, and emphasized the feasibility of PLDα1 and EIN2 overexpression in rice plants, supporting plant breeding programs in the development of drought tolerant genotypes.Item Caracterização dos fatores nutricionais e antinutricionais de sementes de frutos do cerrado(Universidade Federal de Goiás, 2015-05-08) Abreu, Patrícia Almeida de Araújo; Silva, Flavio Alves da; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4413444Y6; Rodríguez, Armando García; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4766392T8; Damiani, Clarissa; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4771335D2; Correia, Márcia Helena Sacchi; Orsine, Joice Vinhal Costa; Damiani, ClarrisaAmong the native species of importance in the Brazilian Cerrado, stand out cagaiteira (Eugenia dysenterica), mama-cadela (Brosimum gaudichaudii Trécul) and mangabeira (Hancornia speciosa Gomes). The use of seeds as co-products becomes alternative for the reduction of organic waste, may be incorporated into formulations of various food products. Thus objective with this study was to evaluate the effect of heat treatment on the technological functional properties, nutritional characteristics and anti-nutritional factors of Cerrado fruits seed meal, namely cagaita, mama-cadela and mangaba submitted to drying at 60 °C and roasts to 110 °C and 130 °C for 10, 20 and 30 minutes compared to the seed in nature. We evaluated the physical-chemical characteristics (color, water absorption index (WAI), water solubility index (WSI), oil absorption index (OAI), milk absorption index (MAI), and milk solubility index (MSI), water activity, pH, soluble solids, total acidity, chemical composition, total energy intake, phenolic compounds, antioxidant potential, mineral profile, cyanogenic compounds, tannins, phytates and trypsin inhibitors). The heat treatment influenced significantly in the different compounds present in cagaita seed meal, mama-cadela and mangaba. In the samples was not detected the presence of cyanogenic compounds. The heat treatment decreased the amount of trypsin inhibitors from samples, and the cagaita mangaba seed meal, compared with the sample in nature. Also influenced the decrease in the phytate content of all samples. In contrast, the thermal treatment increased tannin levels in all evaluated flours. It was concluded, therefore, that the surveyed seed meal has good nutritive value, the presence of significant amounts of minerals from the Recommended Daily Intake (RDI) for adults, pregnant women and children, exhibited bioactive compounds and showed antioxidant activity, and its use is alternatively for the food industry because it has absorption characteristics in water, oil and milk, and solubility in water and milk.Item Crescimento inicial de teca e produtividade de soja sob diferentes adubações em sistema agrossilvicultural(Universidade Federal de Goiás, 2016-03-11) Abreu, Sandro Alex Helrigel; Calil, Francine Neves; http://lattes.cnpq.br/2520537051838618; Calil, Francine Neves; http://lattes.cnpq.br/2520537051838618; Pires, Patrícia Pereira; Chagas, Matheus PeresThe Agroforestry Systems (SAF’s) are models of agricultural exploration that using forest species intercropped with agricultural crops and/or forage with or without animal presence. They have been widely disseminated therefore contribute to the sustainability of the agriculture. This study was developed from an experiment conducted in agrossilvicultural system during the period 2013-2015, the Federal University of Goiás, city of Goiania, GO. The objective of this study was to evaluate the chemical properties of soil, development and productivity of plant components in system integration (Teca and soybean), using different fertilization soil and cropping systems. The experimental design was a randomized block with four replications, in arrangement factorial 4 x 2, consists of four types of fertilization: no application (control); mineral fertilization; application of cattle manure and application of sewage sludge in two cropping systems: single Teca and Teca intercropped with soybeans. The chemical properties of the soil were favored by the application of sewage sludge. There not increase in levels of heavy metals in soil by use of organic waste. The productivity of soybean fertilized with sewage sludge did not differ of the mineral fertilizer, being higher other fertilization. The initial performance of Teca in single cropping was favored by the application of both organic waste. However, when intercropped with soybean, sewage sludge application resulted in higher values of height and diameter at breast height (DBH). The canopy of the tree component of the system was not influenced by the type of fertilizer used, keeping constant the light rate in the different fertilization. The use of sewage sludge is favorable both for the initial development of Teca as plants for soybean yield, being recommended in agrossilviculturals systems.Item Heterogeneidade estrutural na indústria Goiana, 2000-2010(Universidade Federal de Goiás, 2013-09-04) Aguiais, Edilson Gonçalves de; Pires, Murilo José de Souza; Teixeira, Sônia Milagres; http://lattes.cnpq.br/1596947832723945; Teixeira, Sônia Milagres; Wander, Alcido Elenor; Sousa, Alexandre Gervásio deThe purpose of this study is to understand to what extent the phenomenon of structural heterogeneity existing in Goiás industrial economy has affected the structure of earnings and employment in the state of Goiás in the interregnum from 2000 to 2010 . The hypothesis put forward is that, in Goiás, the process of growth of industrial production and the number of companies has developed so as to increase productivity gap and labor income among different segments of the manufacturing industry in the period 2000-2010. To perform the proposed work goal, we used the technical resources of literature and documents and adopted the descriptive analytical method. The first analysis is a comparison between the structure of the transformation of Goiás and São Paulo industry and the results indicated a reduction in structural heterogeneity, both indicators of labor productivity as in the structure of earnings and employment. The second test checks the industrial conformation as the level of technology embodied in the production process. At this point, the segments of low technological intensity remained the largest share of the value added by the manufacturing industry, indicating that driving the dynamic axis of Goiás economy facing the external sector, deepening into a process of specialization in some technologically advanced segments. There, in this period, a process of reduction of intra-sectoral heterogeneity caused by the reduction in labor productivity in sectors with a higher share in the value added of the manufacturing industry and the structure of jobs. Finally, the third analysis captures the structural heterogeneity according to company size, demonstrating an important change since the micro ceases to be the main source of jobs in the Goiás’s manufacturing while indicating a process of increase in average incomes work in the 2000-2010 period. There is, therefore, in this period, an intense process of incorporating labor to the industrial structure, especially in large companies, consortiums to increase our level of average labor compensation, indicating a process of reducing the heterogeneity structure in the manufacturing industry state of Goiás.Item Influência de variáveis macroclimáticas sobre as principais doenças do arroz(Universidade Federal de Goiás, 2016-03-03) Aguiar, Jordene Teixeira de; Lobo Junior, Murillo; http://lattes.cnpq.br/3352833548668460; Lobo Junior, Murillo; Filippi, Marta Cristina Corsi de; Heinemann, Alexandre Bryan; Castro, Adriano Pereira deThe influence of climatic variables on rice diseases was assessed in Brazil. Firstly, it was necessary to validate climate data from remote sensoring, retrieved from NASA’s database Prediction of Worldwide Energy Resource (POWER). POWER data were compared to climate records of surface stations from the National Institute of Meteorology (INMET). Climate data consisted of a time series (2004-2014) of monthly average temperatures and rainfall. Validation tests were carried out with Pearson’s coefficient of correlation and adjustment of linear regression models between the satellite data and surface stations. Further, data accuracy was checked according to average absolute error, root mean square deviation and concordance index. Monthly rainfall from most regions satisfactory correlated with Pearson coefficients between 0.75 and 0.95 (P<0.05). In contrast, maximum and minimum temperatures recorded by satellites showed irregular results that vary by region. In these cases, remote sensing did not detect extreme weather events, such as heavy rainfall or drought. Monthly rainfall comparisons also showed the most consistent results for all regions in accuracy tests. The endorsed data supported the next stage of this work, regarding the effects of climate variables on rice diseases. This investigation counted on a historical series of disease severities recorded in field tests, carried out between 1983 and 2014. Climatic data from INMET, EMBRAPA and NASA/POWER was arranged in a matrix of environmental variables, and tested for correspondence with disease severities recorded in 15 sites for at least eight years. Redundant climate variables were eliminated by principal component analysis. With structured data disposed in two datasets of climate (explanatory variables) and disease severity and productivity (response variables), canonical correlation analysis was performed (CCA) by location and by regions. The influence of climate on disease severity was demonstrated in only five sites, according to CCA models significant at 5%, with their first two axes explaining over than 50% of explanatory variables. In such sites, the total variation in disease severity was partially explained by climate variables. In the regional approach, climate variables did not significantly influence rice diseases in the North Region. Nevertheless, significant models demonstrated the correlation between climatic variables and disease in the Center-West and Northeast, despite the small percentage of explanation by the first two axes. In general, higher disease severity was related to rainfall and lower minimum temperatures during the reproductive stage of rice plots. In all cases, yield was not related to environmental variables.Item Manejo do mofo branco (Sclerotinia sclerotiorum L.) em tomateiro industrial(Universidade Federal de Goiás, 2011-08-30) AGUIAR, Renata Alves de; CUNHA, Marcos Gomes da; http://lattes.cnpq.br/2006008625763742Brazil ranks ninth in the world production of tomato (Solanum esculentum L.), while much of this production is destined for processing industries. The added value obtained with the fruit processing endorses this species as the vegetable with the greatest economic importance in the Cerrado region of Brazil, where the State of Goiás stands out as the largest producer. Despite the favorable soil and climatic conditions, several factors have hindered its production, especially diseases caused by soilborne pathogens, which had increased their importance with the adoption of intensive production systems. Among them, white mold caused by Sclerotinia sclerotiorum (Lib.) De Bary has caused serious problems in infested soils, under mild temperatures and high humidity. Concerning the large number of S. sclerotiorum hosts and the lack of resistant hybrids, chemical control has been chosen as the most common method for disease management, despite not always efficient, due to the difficulties to reach the pathogen s resistance structures in the soil. Therefore, the study aimed to evaluate the disease escape on different tomato hybrids, to compare the effectiveness of synthetic fungicides mixed or not to potassium silicate; evaluate the biological control of white mold, with different commercial products based on Trichoderma spp. associated or not to a synthetic fungicide, and to evaluate the biological control with or without chemical fungicides, applied through chemigation. Tests were carried out in soil of medium texture at Unilever experimental farm, in Goiânia (GO), from 2008 to 2010. The experimental area was previously infested with sclerotia of the pathogen, obtained in pre-cleaning wastes of soybean. Drip irrigation was used in all tests, which had 4 plants m-1 with 1.5 meters between rows. The hybrids used in the disease escape tests were: U232, U2006 (Unilever), H9992, H7155 (Heinz), N877 (Nunhems) and H108 (Hypeel). In all other essays, Heinz 9780 was the chosen hybrid. All experiments were conducted under randomized blocks design with three replications, and had weekly assessments of disease incidence to estimate the area under the disease progress curve (AUDPC). We also evaluated the productivity and its components, as well as acidity, soluble solids content and industrial yield. The results were submitted to ANOVA and to the Scott Knott or Tukey tests at 5%, using the statistical program Sisvar. It was shown that: Hybrids H9992 and Hp108 had lower AUDPCs, suggesting a partial escape to white mold and that hybrid choice can be added to the disease management cultural practices, despite there was no difference on their yield. In 2008, under higher disease pressure, potassium silicate in plots without fungicide application showed disease incidence, AUDPC, productivity and industrial yield equivalent to treatments with fluazinam and procymidone, and superior to results with benzalkonium chloride. There was no difference between treatments with Trichoderma spp. associated or not to fluazinam, in any of the assessed traits. Regarding industrial yield, there was an interaction between Trichoderma, fluazinam and years, with higher pulp yield under higher disease incidence and fluazinam sprayed alone. It was found that biological control with Trichoderma spp. via chemigation as a single measure or in mixture with the synthetic fungicides procymidone fluazinam reduced the AUDPC and increased the productivity of processing tomatoes in 25 tons on average, compared to the control. Therefore, this study showed new options for the integrated management of white mold in processing tomatoes.Item Efeito do manejo do solo com plantas de cobertura, cultivares/híbridos e nitrogênio na cultura do milho(Universidade Federal de Goiás, 2008-02-26) AGUIAR, Renata Alves de; SILVEIRA, Pedro Marques da; http://lattes.cnpq.br/4242408931816325The corn is the main cereal produced in Brazil and its productivity is very affected by the improper use of nitrogen, which is the nutrient absorbed in larger quantities and therefore responsible for a significant share in production costs. Due to the importance of nitrogen for the corn crop becomes necessary studies to reduce the amount of nitrogen applied to the crop, reducing losses and increasing the efficiency of its use, beside minimize environmental risks. One way have been studied to reduce the amount of nitrogen applied and increase the efficiency of use of inorganic nitrogen, from the fertilizer, it is the combination of plants that cover the ground with nitrogened fertilizer. The study aimed to determine the economic viability and the effect of soil management with the use of soil cover plants, hybrids and nitrogen doses in coverage in the vegetative and reproductive characteristics, related to productivity of corn. The corn, in the experiment, was planted at begning of February in the field trial of Embrapa Arroz e Feijão, Red Latosol Distrophic. The experimental design was a randomized complete block with three replicates the arrangement of plots in sub-sub-divided. The plots were formed by four types of soil management: direct planting of corn on the black mucuna stubble (Mucuna aterrima Merr.); direct planting of corn on the of crotalária juncea stubble (Crotalaria juncea L.); direct planting of corn on vegetation spontaneous (aside) and planting corn in the system of conventional tillage (arado of aiveca). The subplots were formed by five doses of nitrogen in coverage: 0, 45, 90, 180 and 360 kg ha-1 of nitrogen in coverage, and the sub-sub-plots of four hybrids of corn: BRS 3003, AG 1051, Green Corn HT-1, HT-2 Green Corn. The analysis of the benefit / cost was performed on the basis of prices of materials and services raised in April 2007. The benefit / cost in the various systems was held in the Excel spreadsheets, and economically viable a relationship exceeding 1.0. It was concluded that: there is effect of hybrid and soil management on vegetative characteristics such as plant height and the first spik and on productive characteristics as income from pulp and grain and mass in a thousand grains of corn, and there is no interaction between hybrid, soil management and dose of nitrogen in coverage of the productivity of corn. The best soil management as the benefit / cost is the fallow without any addition of nitrogen in coverage, followed by the system of conventional tillage with 45 kg ha-1 and without the addition of nitrogen.Item Distribuição da variabilidade genética e fluxo de pólen em subpopulações de Annona crassiflora Mart. (Annonaceae)(Universidade Federal de Goiás, 2015-12-21) Almeida Júnior , Edivaldo Barbosa de; Soares , Thannya Nascimento; http://lattes.cnpq.br/5590256762396056; Soares, Thannya Nascimento; Chaves , Lázaro José; Borba , Tereza Cristina de Oliveira; Collevatti , Rosane GarciaThe Annona crassiflora Mart. species (Annonaceae) is a fruit plant native from Cerrado, widely distributed throughout the biome. The goal here was evaluate the spatial distribution of genetic variability in natural subpopulations of the species, geographically, and relate the genetic diversity levels with climatic and landscape profile, furthermore the pollen dispersal within a subpopulation. We used here six pair of microsatellite primers. To evaluate thedistribution of genetic variability we sampled 25 natural subpopulations, 30.6 plants per subpopulation, on average. We estimate the genetic diversity (He), allelic richness (Ar), fixation index (f), genetic structure, using coancestry coefficient (θ) and inbreeding coefficient of overall population (F). The spatial pattern the genetic variability was evaluated by Mantel test, Moran's I index and linear regression of genetic parameter with two spatial dimensions (latitude and longitude). We correlate He, Ar and f with climate suitability and the percentage of Cerrado vegetation around subpopulations. Furthermore we evaluated the pollen dispersal by paternity analysis, using 572 plants, including 460 seeds, 20 mother plants and 92 pollen donors candidate, within a natural subpopulation. The outcrossing rates were also evaluated in maternal families using the mixed mating model. The outcrossing rates indicate mating system with prevalence of allogamy. The assignment of paternity indicated that gene flow mainly occurs in short distances, until 360 meters, in the subpopulation evaluated. The 25 subpopulations have moderate genetic diversity levels and strong genetic structure. We found inbreeding due to the subdivision, but not in mating within subpopulations. The demes belongs to two consistent groups with genetic discontinuity between the northwest and southeast subpopulations distribution. The genetic diversity and allelic richness showed strong relationship with longitude, suggesting a range expansion in the southeastern direction. We noted that spatial distribution of genetic diversity and allelic richness are related to suitability at the last glacial maximum, by an indirect effect of geographical distances, whereas no relationship was observed regarding present suitability. The percentage of cover natural vegetation, in turn not explain the spatial distribution of genetic diversity, allelic richness and inbreeding coefficient.Item Variabilidade genética quantitativa e molecular em uma coleção de germoplasma de Eugenia dysenterica DC. (Myrtaceae)(Universidade Federal de Goiás, 2012-03-15) Almeida Júnior, Edivaldo Barbosa de; Chaves, Lázaro José; Soares, Thannya Nascimento; http://lattes.cnpq.br/5590256762396056; Soares, Thannya Nascimento; Chaves, Lázaro José; Vasconcellos, Breno de Faria e; Coelho, Alexandre Siqueira GuedesThe cagaiteira (Eugenia dysenterica DC)., is a native species of Cerrado. The plant is known for fruit production, which are used in natura or processed in several ways. It also provides food for the local fauna and, therefore, it conservation is important for maintenance for the communities. In order to maintain the productivity potential of the species, we should invest on plant breeding programs. To support these programs and help the species conservation, it is important to characterize the genetic variability available to breeders, both in germplasm collections and natural populations. This could also help to recommend priority areas to collect and conserve the germplasm. Neutral molecular markers have been used to evaluate the distribution of genetic variability in natural populations. The genetic structure of populations is the result of historical interaction between genetic drift, mutation, and gene flow. To detect the influence of adaptive processes in the genetic differentiation of populations we used 𝑄𝑆𝑇 index. The comparison of 𝑄𝑆𝑇 to the 𝐹𝑆𝑇, for neutral loci, provides values to test hypotheses about the role of natural selection. Therefore, the aim of this study was to characterize the germplasm collection of the cagaiteira from the EA/UFG. We used quantitative traits and microsatellite markers to make inferences about the role of natural selection in the differentiation of the cagaiteira subpopulations of Goiás, Southeast Brazil. Data collected from the quantitative traits were: plant height (AB), height of the first bifurcation (AB), the stem circumference (CC) and mean diameter of the crown projection (DC), leaf length (CL), leaf width (LL), leaf format (FF) and footstalk length (CP). Molecular data were obtained by amplification of eight microsatellite loci. We estimated the following quantitative genetic parameters: heritability and genetic variation coefficient, and the molecular parameters: gene diversity and allelic richness. We compared the probability distributions of the genetic structure parameters for both, quantitative and molecular data (𝑄𝑆𝑇 vs. 𝐹𝑆𝑇). From the quantitative genetic parameters we found modest responses to selection for the traits: AP, CC and DC; and significant responses for CL, LL, FF and CP. It was observed that the samples collected in natural populations are well represented in the germplasm collection, supported by molecular gene diversity. The traits AP, DC and DC are under convergent natural selection, and the traits CL, LL, FF and CP are under divergent natural selection into the cagaiteira subpopulations of Southeast Goiás.Item Qualidade de grãos em feijoeiro-comum: estimativas de parâmetros genéticos, interação com ambientes, eficiência de seleção e correlação entre caracteres(Universidade Federal de Goiás, 2018-06-29) Almeida, Danilo Valente; Melo, Leonardo Cunha; http://lattes.cnpq.br/9132553601896172; Melo, Patrícia Guimarães Santos; http://lattes.cnpq.br/1508679345970114; Melo, Patrícia Guimarães Santos; Melo, Leonardo Cunha; Silva, Fernanda de Cássia; Ribeiro, Nerinéia DalfolloCommon bean (Phaseolus vulgaris L.) is one of the most important crops related to human feeding playing an important role in ensuring food security. Bean is an important source of protein, besides providing considerable amount of fiber and micronutrients as iron and zinc. Thus, the search for genotypes with high nutritional value grains and that meet standards for commercialization is among the objectives of common bean breeding program, specially the carioca grain type one, the preferred, according to the demand for more nutritious and fast foods. Thus, this work has for objectives: I) To investigate the genetic variability and the environment and genotype-environment interaction effects on seed iron (FeC), zinc (ZnC), crude fiber (CF) and protein content (PC), cooking time (CT), grain yield (GY), 100 grain weight (GW), sieve yield (SY), grain color at harvest (GCH) and grain color after 90 days of storage (GCS); II) To evaluate the degree of information of evaluations for grain quality conducted in an environment; III) To estimate genetic parameters and genetic gains for FeC, ZnC, CF, PC and CT; IV) To estimate phenotypic, genetic and environmental correlations between grain quality traits and GY; V) To select advanced common bean lines with carioca grain type superior for grain quality. 81 common bean lines with carioca grain type were evaluated in Preliminary Tests (PT) in triple lattice design 9x9 with plots of two 4-meter rows. In these trials the traits GY, SY and GW were evaluated and FeC, ZnC, CF, PC and CT were evaluated in only one PT. In this trial the phenotypic and genetic parameters and the genetic gains were estimated. The 20 superior lines were selected considering FeC, ZnC, CF, PC and CT and then evaluated in Validation Tests (VT), conducted in 9environments, between 2015 and 2017, in randomized complete block design with 3 replicates and plots of one 4-meters row. Analysis of variance and joint analysis were performed for all the grain quality traits FeC, ZnC, CF, PC, CT, GY, SY, GCH, GCS and GW evaluated on VT. The phenotypic, genetic and environmental correlations were estimated between the traits FeC, ZnC and GY. The phenotypic adaptability and stability parameters were estimated based on the method proposed by Nunes et al. (2005) and the selection of the best genotypes for grain quality was performed based on the index of Mulamba & Mock (1978). The preliminar evaluation of the grain quality traits was efficient and suficient for selecting the superior genotypes for FeC, CF, PC and CT, however, based on the GxE interaction detected, it is recommended to evaluate in at least 2 environments. Significant effects of genotype, environment and genotype-environment were detected for all the traits evaluated on VT. Based on the genetic variability detected, genetic gains can be obtained with the selection for FeC, ZnC, PC and CT, but for CF the available variability is a challenge to obtain important gains. The phenotypic and genetic correlations between FeC and ZnC were significant, wich indicate simultaneous gains for these traits. The lines CNFC 16627, CNFC 16518, CNFC 16602, CNFC 16615 and CNFC 16520 can be used for the improvement of carioca grain quality.Item Efetividade social do programa bolsa família na segurança alimentar das famílias rurais no município de Rio Verde (GO)(Universidade Federal de Goiás, 2014-06-11) Almeida, Frankcione Borges de; Almeida, Luiz Manoel de Moraes Camargo; http://lattes.cnpq.br/5053214724598522; Almeida, Luiz Manoel de Moraes Camargo; Oliveira, Adriano Rodrigues de; Ribeiro, Francis Lee; Souza, Cleonice Borges deThis research had the objective to evaluate management efficacy, to identify institutional and organizational obstacles and the effectiveness of Bolsa Família Program for the alimentary safety of rural families assisted in the municipality of Rio Verde (GO). In order to achieve the proposed goals, the study is supported by literature review and quantitative and qualitative analysis of the data collected in the field research. The study is structured in five chapters, including the introduction. In the second chapter, the theoretical and methodological aspects are presented, followed by a discussion of public policies, transfer payment policies, evaluation of public policies, alimentary safety and rurality. In the third chapter, we present the general aspects of Bolsa Família Program and secondary data obtained from the official agencies of the program in the researched empirical universe. In the fourth chapter, we present the analysis and discussion of the data about alimentary safety and Bolsa Família Program in the researched universe and in the fifth, our conclusion. 94 rural families, all beneficiary of the program, were interviewed through the application of a semi-structured questionnaire. Besides, interviews were carried out with the local managers of social assistance, education and health with the aim of evaluating management. The data collection and analysis allowed us to present the socioeconomic and sociodemographic profile of the subjects and their perception of the program and of the agencies in charge. There is prevalence of mild alimentary insecurity in 54,25% of the researched families, measured by the Brazilian Scale of Alimentary Insecurity (EBIA). The results allowed the evaluation of the efficacy and the identification of the obstacles in the municipal management in the acting axis of Bolsa Família Program, as well as proposing specific conditionalities of the program for the rural environment.Item Variabilidade morfoagronômica da coleção de germoplasma de mangabeira (Hancornia speciosa Gomes) da Universidade Federal de Goiás(Universidade Federal de Goiás, 2015-08-28) Almeida, Gabriella Queiroz de; Telles, Mariana P. Campos; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4707329E5; Chaves, Lázaro José; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783820E2; Chaves, Lázaro José; Peixoto, Nei; Coelho, Alexandre Siqueira GuedesThis study aimed to characterize the Mangaba (Hancornia speciosa Gomes) Germplasm Collection owned by the Universidade Federal de Goiás, by measuring 40 morpho-agronomic characters. The collection was designed in randomized blocks with 57 treatments (progenies) and four replications, totaling 192 individual accesses, which represent 29 natural populations and four botanical varieties. The variance components estimation was done using random model, and REML procedure, considering the effects of botanical varieties, populations within varieties, progenies within populations and individuals within progenies. Considering 40 morpho-agronomic characters, it was observed that there is significant genetic variability in seven characters among the progenies, 24 characters among the populations and 18 characters among botanical varieties. In addition, individual heritability was higher than 50% in 21 of them. The highest percentual individual selection gain was estimated for the character number of fruits produced by each plant. Significant correlation in some biometric characters between young and adult plants was noticed, including their productivity, which suggests the possibility of early selection. Among the 55 genetic correlations among the agronomic characters, 25 were significative. The fruit production peak occurred between June and October, H. speciosa var. cuyabensis being the most productive one. Multivariate analyses results showed that H. speciosa var. speciosa is the most genetically different in comparison with the others. The characters suggested as minimum quantitative descriptors for the Mangaba tree were: leaf length and width, petiole length and diameter, length between the knot, corolla diameter, flower peduncle diameter, fruit length and diameter, number of fruits, plant height and first branching heightItem Investigação do processo oxidativo avançado (UVC/ H2O2/Carvão ativado) na eliminação de Ftalatos(Universidade Federal de Goiás, 2017-05-05) Almeida, Maria Carolina de; Sá, Fernando Pereira de; http://lattes.cnpq.br/4037828435725730; Oliveira, Tatianne Ferreira de; http://lattes.cnpq.br/2017895913160804; Oliveira, Tatianne Ferreira de; Goulart, Gilberto Alessandre Soares; Pereira, Julião; Castiglioni, Gabriel Luis; Silva, Flávio AlvesThe objective of this work was to compare the efficiency of conventional treatments such as activated carbon (AC) Adsorption and the advanced oxidation process (AOP), UV-C/H2O2, for degradation of diethyl phthalete (DEP) and coupling UV-C/H2O2/AC in laboratory effluent, ultrapure water and faucet water doped with DEP and laboratory effluent with multicomponents (DEP and phenol). The chemical characterization (Boehm method, pHPZC, IRTF, elemental analysis) and physical (volume of micropores and mesopores, mean micropore width by the Dubini-Radushkevich method were used as a predecessor to the kinetic adsorption study, Surface area and microporous specific volume by the alpha method, microporous and total surface, BET surface area by BET method, cumulative mesopore distribution and pore volume, cumulative area and surface area and pore size by BJH method) of AC. The factorial design with eleven tests and three independent variables (AC mass, temperature and pH) was applied, resulting in response surfaces for adsorption capacity, DEP elimination rate and equilibrium time without significant difference between the studied variables. Mathematical modeling of adsorption kinetics using the pseudo-first, pseudo-second order and intraparticle models was performed and the pseudo-second order model was fitted to the experimental kinetic adsorption data. It was followed by the study of the adsorption isotherms for the lower, intermediate and longer equilibrium experimental conditions. It was performed the mathematical modeling of the adsorption isotherms using the Langmuir and Freundlinch models, and adjusted to the Freundlinch model to the experimental data of the adsorption isotherms with higher determination coefficients (R2), confirming the predominant chemorandomization adsorption phenomenon. The treatment of AOP UV-C/H2O2 was then applied alone. The factorial design with eleven tests and three independent variables (H2O2 concentration, temperature and pH) was applied, resulting in surfaces of responses to DEP elimination rate with significant difference between the variables studied for pH, positive effect of H2O2 concentration (p < 0.5). The mathematical modeling of the kinetics of AOP using the first order models was carried out, and the kinetic experimental data of the photodegradation with high coefficients of determination (R2> 0.9) were fitted to the model. The degradation kinetics of DEP by AOP coupling and AC, UV-C/H2O2/AC were followed. The factorial design with eleven tests and three independent variables (H2O2 concentration, temperature and pH) and with 0.4 g of AC, resulting in surfaces of responses to elimination rate of DEP with significant difference between the variables studied for pH, positive effect of H2O2 concentration (p <0.5). The mass of AC was determined in 0.4 g for all eleven tests, because it was the mass applied at the highest rates of elimination of DEP by kinetics of Adsorption, which was confirmed by repeatability at the central points of the factorial design (C9, C10 and C11). The catalytic activity of the carbons for the Adsorption process in the presence of tertbutanol was high, however, after the determination of the kinetic parameters, the contribution was higher for photooxidation of DEP by the action of the AOP (homogeneous system).Item Ocorrência de nematoides na cultura da banana no estado de Goiás e sua correlação com o mal-do-Panamá e com fatores edáficos(Universidade Federal de Goiás, 2016-03-22) Almeida, Nayane Oliveira; Rocha, Mara Rúbia da; http://lattes.cnpq.br/4660306671671575; Teramoto, Adriana; Lobo Júnior, Murillo; Rocha, Mara Rúbia daThe problems caused by nematodes and by the Panama disease on banana plantations are responsible for production losses and limiting to its cultivation. In the state of Goiás there is few information about the nematode genus that affect this crop, and its relationship with the incidence of the fungus Fusarium oxysporum f. sp. cubense (Foc). This research aimed to survey the occurrence of plant parasitic nematodes, the incidence of Foc and soil attributes, and determine if there is a correlation among these factors. In January 2015, twelve banana producing regions in the state of Goiás were sampled: Anápolis, Caiapônia, Goiatuba, Itaguaru, Itumbiara (two areas), Jataí, Morrinhos, Ouro Verde, Palestina, Taquaral and Uruana. All sampled areas, except Morrinhos, revealed contamination with Foc, and all had different genus of nematodes. Meloidogyne sp., Helicotylenchus sp. and Rotylenchus sp. were the main genus of plant parasitic nematodes present in the banana plantations, with Meloidogyne sp. and Rotylenchus sp. the most dominant and abundant genus. We found that Pratylenchus sp. increases the population levels of F. oxysporum and that Helicotylenchus sp. has been affected by the concentration of P, Ca, Mn and the soil pH.Item Análise da competitividade potencial da cadeia exportadora de feijões brasileira(Universidade Federal de Goiás, 2012-04-25) ALMEIDA, Paulo Roberto Vieira de; FIGUEIREDO, Reginaldo Santana; http://lattes.cnpq.br/1098394550647665; SOUZA, Eliane Moreira Sá de; http://lattes.cnpq.br/4454182958023791; WANDER, Alcido Elenor; http://lattes.cnpq.br/8250997651281553Beans are an important component in the Brazilian diet and various countries across the globe. In Brazil is grown by farmers in various profiles at different scales, regions and farming systems. Brazil has a problem with self-sufficient in beans, historically presented as a major importer of grain, has a low market share in world exports that occurs far from the fact that these markets consume certain types of beans that Brazil has no tradition of produce, the type that is predominantly produced and consumed in Brazil is common bean. The international market beans can be better explored, but is necessary to organize the national production chain. Because of the importance of beans in the Brazilian domestic market, and low expression in exports, we chose to analyze the potential competitiveness of the export chain of brazilian beans. The competitive analysis contemplated the production sector and the export sector, it was developed through 9 drivers and 48 sub-factors that together indicate how is the condition of potential competitiveness of the chain. The evaluation was conducted from the perspective of key players and use of secondary data. Through the data collected it was found that the bean export chain is not currently so structured as other commodities, the production of exportable grain is still insufficient, there are difficulties in finding producers with production that meets the requirements of foreign markets, there are few producers with high production capacity, we observed the presence of active medium and high specificity and the level of informality in the chain is high. The worst drivers in the production sector were on account of the institutional environment, market relations and conditions of the logistics and storage, already in the export sector the driver institutional environment presented negative condition of competitiveness. The computer simulations performed using the events selected by experts showed that the conditions for improvements in the medium term has a greater positive effect on the export sector than in production sector, the negative effect of tax rates affects more than the production sector while technological improvements have multiple positive effects on other indicators. The results indicate that some drivers link that the profits are more concentrated in the export sector and because of the production costs are higher, the condition of competitiveness in production sector is more negative, nevertheless the general condition of competitiveness of the chain is positive and indicates that is interesting to invest in export of beans, though some interventions should be made to improve the indicators of the production sector.Item Pesquisa de listeria monocytogenes em linguiças do tipo frescal(Universidade Federal de Goiás, 2014-02-25) Almeida, Thatyana Lacerda de; André, Maria Cláudia Dantas Porfirio Borges; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Borges, Liana Jayme; Rezende, Cintia Silva Minafra e; Campos, Maria Raquel HidalgoStudies conducted in Brazil showed the presence of pathogenic bacteria in foods whose consumption can cause diseases and food-borne disorders. In general, consumers have expectations about consuming safe food and foodborne diseases are highly unpleasant, generating distrust in the quality of food products on the market. Listeria monocytogenes is an important pathogen transmitted by food, whose accurate identification is important for the correct risk determination associated with the ingestion of various kinds of food. Considering the importance of this pathogen to the consumer, the present study aimed to isolate and identify Listeria monocytogenes in frescal type of sausages, butchers sold in the city of Aparecida de Goiânia Goiás. 88 samples were analyzed, been 44 frescal type of pork sausage and 44 of chicken meat from the butchers of Aparecida de Goiânia, registered in the Comércio Varejista de Carnes Frescas in Goiás. Was followed the methodology of sampling and analytical recommended by the American Public Health Association, and the analyzes were performed at the Laboratório de Controle Higiênico Sanitário de Alimentos da Faculdade de utrição da Universidade Federal de Goiás. Of the total samples, six were considered suspicious and inteneded with biochemical evidence, none were considered positive for the target bacteria. The results obtained in this research found a quality sausages for the target bacteria, but must be reinforced the need for legal support to facilitate recognition of research actions broader control and disease severity dissemination, especially in pregnant women, newborn born, immunocompromised and elderly who are the most vulnerable population.Item Eficiência da seleção para qualidade da fibra do algodoeiro (Gossypium hirsutum)(Universidade Federal de Goiás, 2018-11-29) Alvarenga, Luís Gabriel Silva; Silva Filho, João Luis da; http://lattes.cnpq.br/0608088933335198; Resende, Marcela Pedroso Mendes; http://lattes.cnpq.br/2080097211870591; Resende, Marcela Pedroso Mendes; Silva Filho, João Luis da; Tarazi, Roberto; Chaves, Lázaro JoséCotton fiber is the main feedstock used in the world textile industry. It is determined by several traits of complex inheritance, influenced by the environment, and which can be negatively correlated with each other, hindering genetic gains in selection for fiber quality. The aims of this study were to estimate genetic parameters for traits related to cotton fiber quality; propose a graphical method to measure the gain with the selection using different intensities of selection; and to verify the viability of SCI and CSP as selection indices for fiber quality. From the cross between the cotton cultivars BRS 336, conventional with high quality fiber, and DP 164 B2RF, transgenic with medium quality fiber, two populations were carried out: one using the bulk breeding method, and another from the backcross with the cultivar BRS 336. Fiber samples of F5:6 (bulk) and F3:4RC3 (backcross) progenies were analyzed using HVI apparatus, which evaluates the fiber quality by measuring the traits length (C), maturity (MAT), uniformity (U), micronaire (MIC), elongation (ELG), short fiber index (FC), resistance (R), degree of yellowing (b), the spin-consistency index (SCI) and the reliability index (CSP). Genetic variability was observed among progenies for R, MIC, ELG, C and FC, confirming the complexity of these traits. The means of the two populations met the needs of the industry, indicating the presence of genotypes with commercial potential. Estimates of heritability ranged from 3.29% (Rb - F5:6) to 59.92% (C - F3:4RC3). All traits showed genetic correlations with at least one trait, and negative correlation was observed between C and the traits PF, MIC, MAT and FC. The CSI index presented a negative correlation with FP, MAT and FC, and positive correlation with C and R. The SCI index showed a negative correlation with MIC and MAT, and a positive correlation with C. The selection of the 20% best progenies using both indices presented favorable responses for C, R and FC, with expected reduction in FP, and without significant influence on the other traits. The graphs of the correlated response were more informative than the estimates obtained through the equation, since they do not need the values of genetic correlation, and allow the analysis considering several intensities of selection. The graphs of heritability showed that the selection gains were reduced or negative for some traits as the selection intensity increased. The strategy of using the gain graphs using different intensities of selection is efficient and easy to be implemented by breeding programs, especially when the objective of the program is to evaluate complex traits, influenced by other characters, such as cotton fiber quality.Item Escurecimento de grãos em feijão: parâmetros genéticos e fenotípicos, associação com tempo de cocção, seleção assistida por marcadores e obtenção de linhagens elite(Universidade Federal de Goiás, 2015-03-31) Alvares, Renata Cristina; Melo, Patrícia Guimarães Santos; http://lattes.cnpq.br/1508679345970114; Melo, Patrícia Guimarães Santos; Bruzi, Adriano Teodoro; Silva Filho, João Luís da; Souza, Thiago Lívio Pessoa Oliveira de; Ganga, Rita Maria DevósThe breeding of common bean cultivars with Carioca grain, slow grain darken-ing, upright plant architecture, and high yield has become a growing challenge. Slow grain darkening will increase the storage time, providing flexibility for producers for the time of sale, and consequently increasing profitability. Studies have demonstrated the existence of genetic variability for this trait, allowing the selection of lines with slow grain darkening. The objectives of this study were i) to estimate genetic and phenotypic parameters of lines of four segregating common bean populations; ii) select those with slow grain darkening, upright plant architecture and high yield; iii) seek an association between slow darkening and cooking time of grains after storage; iv) evaluate two induction methods of grain dark-ening and v) validate the markers Pvsd-1158 and PVM02TC116, associated with grain darkening. The tested lines were derived from four segregating populations resulting from crosses between the cultivar BRSMG Madrepérola with slow grain darkening and the par-ents BRS Estilo, BRS Cometa, BRS Notável, and CNFC 10429. Three trials were installed with 220 lines (55 per population), and 5 parents in a 5x15 triple lattice design, with plots of two 3-m rows, at three locations. The experiments were conducted in the winter grow-ing season 2012, one in Santo Antônio de Goiás and two in Brasilia. The traits grain yield, plant architecture, grain darkening, 100-grain weight, and cooking time were evaluated. The variance components and genetic and phenotypic parameters were estimated, and the phenotypic, genetic and environmental correlation coefficients between grain darkening and cooking time, 90 and 180 days after harvest. Induction methods of accelerated and slow darkening were compared. From the markers Pvsd- 1158 and PVM02TC116, identi-fied as previously linked to the gene that controls grain darkening, the frequency of recom-bination and selection efficiency of the markers was estimated for each population and environment and in the mean of the environments. For slow grain darkening, the estimates of heritability, genetic variance and expected gain with selection were high, indicating good chances of successful selection. For yield, plant architecture and commercial grain size, the estimates of heritability and genetic variance were high, but indicated no high gains with simultaneous selection. Lines with slow grain darkening were obtained from the four populations; the highest number of lines that combined slow darkening with upright plant architecture, high yield, and commercial grain size were derived from the crosses BRSMG Madrepérola x BRS Estilo and BRSMG Madrepérola x BRS Cometa. No im-portant genetic correlation between grain darkening and cooking time was identified, there-fore, light-colored grains do not indicate a short cooking time. The induction methods of slow and accelerated darkening, provide similar information in the discrimination of lines with slow and regular darkening. The estimates of the recombination frequency for marker Pvsd-1158 were always low, indicating the close linkage of this marker to the gene that controls slow darkening, and were stable in the different environments and populations. Marker PVM02TC116 however was not polymorphic in three of the four populations. The recombination frequency of this marker in the polymorphic population was high, showing that it is unsuitable for marker-assisted selection for grain darkening.Item Adição de pó de aciaria como fonte de micronutrientes e diferentes níveis de calagem em solos de cerrados cultivados(Universidade Federal de Goiás, 2010-02-26) Alves Filho, Anibal Sebastião; Dornelles, Milton Sergio; http://lattes.cnpq.br/9601151044965568; Leandro, Wilson Mozena; http://lattes.cnpq.br/9052207260053937; Ximenes, Paulo Alcanfor; Borges, Jácomo Divino; Barros, Rosana Gonçalves; Menezes, Luiz Antônio Silva; Leandro, Wilson MozenaThe savannas reached prominence in the development of corn (Zea mays L.), soybean (Glycine max L.) and processing tomato (Lycopersicum esculentum Mill.), Depending on the economic and social importance of these crops. The problems of acid soils and nutrient deficiency in the savannas are common in most soils, but once overcome these obstacles, the cultures exhibit satisfactory development and production. Increasingly it becomes necessary, by the dynamism that modern agriculture provides that alternative mechanisms of replenishment of nutrients to the soil are offered, due to the high cost of fertilizer and high extraction of these elements in each cycle of crops. The use of industrial waste from various sources has shown potential for agricultural use, for purposes of correction of acidosis, addition of macro and micronutrients to the soil or even physical conditioning of the soil, always under careful criteria used to avoiding the environmental contamination. The aim of this study was to evaluate the effect of the electric arc furnace dust coming from the steel industry as a source of micronutrients in crops of corn, soybean and tomato at different levels of liming. The tests were conducted in two locations. A field experiment was conducted at the experimental farm of the School of Agronomy and Food Engineering, Universidade Federal de Goiás, Campus Samambaia, in Goiânia-GO, Brazil and other, in a greenhouse at Palmital Farm, municipality of Urutaí-GO, in campus of the Instituto Federal Goiano. During three years, were evaluated in Goiânia-GO, the use of steelmaking dust in corn in rotation with soybean and, in Urutaí-GO, for seven months, the tomato crop in succession with soybeans. The results in both experiments indicated that the levels of heavy metals detected in soil and leaves of the plants analyzed were below the limits considered toxic.
