SNP-based genetic diversity of a network of germplasm banks to establish a core collection for the tropical fruit Hancornia speciosa
(2025) Souza, Juliana Lopes; Alcântara, Bianca de Sousa; Chaves, Lázaro José; Rocha, Fernando Souza; Silva Junior, Josue Francisco da; Muniz, Ana Veruska Cruz da Silva; Silva Junior, Orzenil Bonfim da
Hancornia speciosa is a tropical fruit and an important food resource native to Brazil. Its fruits, commercialized in natura or as a frozen pulp or ice cream, are an outstanding source of vitamins C, E, folates, and carotenoids. Despite its economic relevance, the species is still exploited in an extractive manner by harvesting natural populations, and no commercial varieties are available. A network of germplasm banks has been established from seeds and vegetative material collected in different regions throughout the Brazilian Atlantic Forest and Cerrado biomes. Nonetheless, resources are limited to maintain and evaluate all germplasm accessions for plant breeding. We used SNP markers generated by DArTSeq to assess the genetic diversity and population structure of 508 individual plant accessions conserved across three germplasm banks of H. speciosa and proposed a core collection for the species to be targeted for phenotypic characterization efforts. Significant genetic differentiation was found among the germplasm banks (Fst 0.221), with moderate genetic diversity and substantial inbreeding within each one, likely resulting from a Wahlund effect due to within-bank substructure as genetic entries were sampled from disjunct populations. A structure analysis assigned most of the germplasm accessions to two genetic groups, although some admixed individuals were observed. A core collection of 138 accessions (27.11%) was proposed, covering 98% of the currently conserved genetic diversity in the germplasm network. Although the proposed core collection provides a solid representation of the currently conserved genetic diversity for breeding, our results indicate that additional sampling of natural populations not yet surveyed should be pursued.
A framework for building enviromics matrices in mixed models
(2025) Trevisan, Bruno Achcar; Junqueira, Vinícius Silva; Florêncio, Bruna de Mello; Coelho, Alexandre Siqueira Guedes; Marcatti, Gustavo Eduardo; Resende, Rafael Tassinari
This study unravels a framework for constructing enviromics matrices within mixed models to integrategenetic and envirotypic data, enhancing phenotypic predictions in plant breeding. Enviromics leveragesdiverse data sources, such as climate and soil, to characterize genotype-by-environment (G×E) interac-tions. The approach uses block-diagonal structures in the design matrixZto incorporate random effectsfrom genetic and envirotypic covariates across trials. The covariance structure is modeled through theKronecker product of the genetic relationship matrixAand an identity matrixIrepresenting envirotypiceffects, effectively capturing both genetic and environmental variability. This dual representation facili-tates more accurate predictions of crop performance (y) across environments, enabling improved selectionstrategies in breeding programs. The framework is compatible with widely used mixed model software,including rrBLUP and BGLR, and is adaptable to account for more complex interactions. By integrat-ing genetic relationships (A) and environmental influences (Z), this approach provides a robust tool foradvancing G×E studies and accelerating the development of superior crop varieties.
Harnessing fuzzy logic for adaptive and stable selection of upland rice lines
(2025) Maciel, Douglas de Oliveira; Guimarães, Paulo Henrique Ramos; Melo, Patrícia Guimarães Santos
Abstract: Fuzzy logic enables automated decision-making and classifies genotype suitability across environments. This study assessed the adaptability and stability of upland rice genotypes using fuzzy logic. To do so, eight lines from the Federal University of Goiás, 10 from the Federal University of Lavras, and two commercial cultivars were evaluated for grain yield, plant height, and flowering days in 13 environments in Goiás. The trials used a randomized complete block design with three replications. Adaptability and stability were analyzed using fuzzy controllers, which classified genotypes into four groups: general adaptability, poorly adapted, favorable, and unfavorable environments. The CSD 08004 line exhibited broad adaptability and stability for yield and plant height and was close to general adaptability for flowering days, making it suitable for cultivation in Goiás.

Genetic parameters and indirect selection of elite lines for efficiency in symbiotic nitrogen fixation in black common bean
(2025) Costa, Nayana Valéria; Melo, Patrícia Guimarães Santos; Pereira, Helton Santos; Sousa, Renato Gomide de; Ferreira, Enderson Petrônio de Brito; Knupp, Adriano Moreira; Melo, Leonardo Cunha
This study aimed to evaluate whether managing populations and progenies of black common bean (Phaseolus vulgaris L.) in exclusive symbiotic nitrogen fixation (SNF) systems, which refer to environments where the primary nitrogen source in the soil is the SNF, is efficient for selecting lines with high symbiotic performance, using grain yield as a selection criterion, and to verify the relationship between agronomic- and SNF-related traits. A total of 76 black common bean lines from a single population and five checks were evaluated during the winter seasons of 2021 and 2022 under SNF systems. The experimental design was a 9 × 9 triple lattice. Evaluated traits included yield, 100-seed weight, and grain appearance. The top 10 and bottom 10 lines were selected based on grain yield in the field and evaluated with rhizobia inoculation in two greenhouse trials with five checks, using a randomized block design with four replications. Traits assessed included chlorophyll content, shoot and root dry weight, nodule number, nodule dry weight, and specific nodule weight. Genetic variability among the lines allowed for the selection of genotypes with high symbiotic performance. Significant differences were found between the groups of top and bottom lines for specific nodule weight, indicating its potential as a selection indicator. Significant correlations were found among the traits. Specific nodule weight, chlorophyll content, and shoot dry weight were identified as key factors for the indirect selection of genotypes with better symbiotic performance. Eight lines were selected for advanced trials to develop black common bean cultivars for SNF.
Prediction-based breeding: modern tools to optimize and reshape programs
(2025) Fritsche-Neto, Roberto; Resende, Rafael Tassinari; Olivoto, Tiago; Abadillo Velasco, Julian Garcia; Nascimento, Moysés; Bahia, Marco Antônio Marcelino; Jarquin, Diego; Vieira, Rafael Augusto
Prediction-based breeding reshapes plant genetic improvement by prioritizing the predictive ability of models over causal interpretation. This review examines recent advances in the use of tools such as genomic selection, high-throughput phenotyping, multi-omics integration, and enviromics to enhance genetic gain and improve the efficiency of breeding programs. Predictive models, while powerful, rely on validation within the genetic and environmental domains represented in the training set, with evident risks when extrapolated to unrelated scenarios. Traditional approaches such as marker-assisted selection and genome-wide association study remain limited for quantitative traits, reinforcing the need for prediction-oriented models. Moreover, the expansion of omics data sources, although capturing greater biological complexity, must be accompanied by rigorous validation practices to avoid fragile interpretations. Stochastic simulations are a strategic tool for testing selection schemes, optimizing training populations, anticipating overfitting risks, reducing costs, and guiding decisions based on prospective scenarios. This review also highlights the importance of ensuring independence between calibration and prediction, focusing on practical accuracy evaluation, and prioritizing operational utility over mechanistic explanation. In summary, prediction-based breeding is a core strategy for modernizing breeding programs, connecting computational tools, high-dimensional data, and pragmatic decision-making to deliver consistent results.
Predictive ability of enviromic modeling in G × E interactions for upland rice site recommendations
(2025) Bahia, Marco Antônio Marcelino; Marcatti, Gustavo Eduardo; Breseghello, Flávio; Melo, Patrícia Guimarães Santos; Dias, Kaio Olimpio das Graças; Yunbi, Xu; Resende, Rafael Tassinari
Enviromics is an omics approach that investigates a phenomenon using all available environmental information. This study explores the use of envirotypic covariates (ECs) to assess genotype-by-environment (G × E) interactions in upland rice in Brazil, using data from 143 locations over 27 years, covering diverse environmental conditions. The platforms WorldClim, NASA POWER, and SoilGrids were used to extract data, resulting in 383 envirotypic covariates. This study aimed to evaluate enviromic kernels that combine GIS and genetic data to predict upland rice productivity across Brazil. We also sought to identify the optimal number of ECs required to ensure model accuracy and stability. The predictive abilities of the enviromic model peaked with around 81 ECs, stabilizing when all 383 were included, suggesting the importance of a comprehensive dataset for accurate predictions. Analysis reveals that environmental dissimilarities are more critical than geographical distance for genotypic variability, reinforcing the need to consider multiple covariates in predictive models. Heritability mapping revealed spatial variations, with regions of high heritability concentrated in southern Brazil, where genetic selection may be more efficient. The clustering of mega-environments was not efficient, highlighting the complexity of G × E interactions, and confirming that pixel-by-pixel enviromic models are a safer approach for recommending breeding actions for upland rice. This study suggests strategies to improve genotype selection for specific conditions, guiding the expansion of rice cultivation into new agricultural areas in Brazil. The findings also contribute to rice-growing regions worldwide, especially in countries cultivating upland rice under diverse conditions.
Genetic gains and field validation of synthetic populations in tropical maize using selection indexes and REML/BLUP
(2025) Sousa, Antonia Maria de Cassia Batista de; Resende, Marcela Pedroso Mendes; Crispim Filho, Ailton Jose; Miranda, Glauco Vieira; Reis, Edésio Fialho dos
The development of tropical maize populations with high heterosis potential is essential for sustaining genetic progress in hybrid breeding programs, yet accurate selection remains challenging due to genotype–phenotype interactions and inbreeding depression. This study evaluated the efficiency of five selection strategies in recurrent selection programs using F2 populations derived from commercial maize hybrids: Smith–Hazel Index (SHI), Base Index (BIA), Mulamba–Mock Index (MMI), REML/BLUP for grain yield (BLUP_GY), and REML/BLUP for inbreeding depression (BLUP_ID). Consistency among methods was assessed with a heatmap, and predicted genetic gains were compared with realized field performance. Predicted gains were highest with MMI and BIA for grain yield and ear weight, although realized results revealed discrepancies, particularly for BLUP-based approaches. Notably, BLUP_GY, which had the lowest predicted yield (4025 kg ha−1), achieved a realized yield of 5620 kg ha−1, surpassing BIA and SHI. This indicates that additive potential was underestimated in predictions, likely due to dominance and environmental effects in early F2 cycles. Overall, BLUP-based methods proved effective in identifying progenies with higher additive value, and their integration with phenotypic indices is recommended to combine short-term realized gains with sustained genetic improvement.
Leaf traits and intraspecific niche models support two main botanical varieties of Hancornia speciosa Gomes (Apocynaceae)
(2025) Morais, Gabriela Corrêa; Francisconi, Ana Flávia; Chaves, Lázaro José; Ganga, Rita Maria Devós; Resende, Rafael Tassinari; Oliveira, Giancarlo Conde Xavier; Zucchi, Maria Imaculada
Hancornia speciosa Gomes (mangabeira or mangaba tree) is a Brazilian plant genetic resource with food, pharmacological, and rubber production potential. However, uncertainty remains regarding the number of botanical varieties within the species. This study aimed to validate how many and which infrataxa can be recognized based on morphological and morphometric leaf traits, environmental suitability areas, and ecological niche overlap. Leaves of H. speciosa var. cuyabensis, H. speciosa var. gardneri, H. speciosa var. pubescens, and H. speciosa var. speciosa were obtained from the Mangabeira Germplasm Collection of the Federal University of Goiás (Goiânia, Goiás, Brazil). Ecological Niche Modeling was performed using compiled occurrence records for each botanical variety extracted from scientific publications and bioclimatic variables provided by WorldClim. We found a clear differentiation of H. speciosa var. speciosa in terms of leaf size and shape. Additionally, patterns observed in ecological niche models, Schoener’s D metric, and the similarity tests emphasize the ecological distinction of this botanical variety. In the future, approaches based on high-throughput sequencing and genome-scale analysis may help detect genomic signatures of local adaptation and provide a better understanding of the evolutionary mechanisms within the species. Based on our findings, we propose the existence of at least two main groups in H. speciosa: one consisting exclusively of H. speciosa var. speciosa, and another comprising H. speciosa var. cuyabensis, H. speciosa var. gardneri, and H. speciosa var. pubescens. Expanding our understanding of this infraspecific classification is essential for guiding conservation strategies, breeding programs, and the sustainable use of mangabeira.

(2025) Miguel, Guilherme Martini Souza Nunes; Ribeiro, Alline Emannuele Chaves; Morgado, Cristiane Maria Ascari; Bueno, Gisana Cristina Alves; Gonçalves, Marcella Elyza Teodoro; Briceno, Julio Cesar Colivet; Silva, Flavio Alves da; Caliari, Márcio; Oliveira, Tatianne Ferreira de
This study aimed to evaluate the biometric characteristics and soluble solids of sugarcane produced in three municipalities in Goiás (Orizona, Alexânia, and Goiás), focusing on the relationship between these variables and their implications for cachaça production. Biometric analyses were conducted on sugarcane fields at full maturation stage, consid-ering variables such as plant height, stalk diameter, average weight, and number of leaves. In addition, soluble solids were measured in Brix degrees, reflecting the sugar content in the stalks. Principal Component Analysis (PCA) revealed distinct variability patterns between the production sites, with three principal components explaining 87.69% of the total variance. The analysis indicated that biometric characteristics, such as stalk diame-ters and average weight, had greater importance in plants from certain locations, while soluble solids showed a negative correlation with the production site. This study provides crucial information for improving the quality of sugarcane for cachaça production, emphasizing the importance of managing biometric characteristics and soluble solids to optimize the final product quality.

(2025) Maria, Zamira Abel de Jesus; Almeida, Maria Carolina de; Briceno, Julio Cesar Colivet; Silva, Flávio Alves da; Sá, Fernando Pereira de; Caliari, Márcio; Oliveira, Tatianne Ferreira de
The objective of this work was to evaluate the chemical composition of by-product flours for the development of dog biscuits. 5 formulations were prepared with 0%, 5%, 10%, 15% and 20% replacement of baru by-product flours. Defatted pie flour contains high levels of protein (25.93 g 100 g-1) and lipids (24.89 g 100 g-1), but low in total fiber (6.15 g 100 g-1). Baru bark flour had low lipid (1.0 g 100 g-1) and protein (5.34 g 100 g-1) contents, but high total fiber content (59.67 g 100 g-1). The levels of total phenolic compounds vary from (14525 and 12532 mg EAG g 100 g-1) with emphasis on baru peel flour. The predominant nutrients in the cookies were carbohydrates (56.49 to 51.20 g 100 g-1for cookies made with baru bark flour (BCB) 52.78 and 49.62 for cookies made with degreased pie flour baru (BTDB), followed by lipids (21.67-23.53 g 100 g-1for BTDB and 19.05-22.33 g 100 g-1for BCB) and protein (12.10-15.05 for BTDB g 100 g-1and 11.23 and 12.19 for BCB g 100 g-1), the study highlights the importance of using by-products in the development of dog food products.
Perfil químico, antioxidante e cromatográfico de cachaça envelhecida em tonéis de carvalho americano, castanha-do-pará, amburana e bálsamo em 12 meses
(2025) Mendes, Dianiny de Cássia Sousa; Freitas, Renata Carvalho de; Miranda, Bruna Melo; Morgado, Cristiane Maria Ascari; Briceno, Julio Cesar Colivet; Silva, Flavio Alves da; Caliari, Márcio; Oliveira, Tatianne Ferreira de
This study evaluated the impact of ageing in American oak, Brazil nut, amburana and balsam barrels on the chemical, antioxidant and chromatographic profile of cachaça over 12 months. The newly distilled cachaça used had an alcoholic strength and higher alcohol content above the legal limits, while the other parameters complied with MAPA Normative Instruction 13/2005. The furfural content showed significant variations during ageing, with increases of 161.84% (oak), 247.30% (chestnut), 233.33% (amburana) and 192.68% (balsam). The chestnut, amburana and balsam barrels, being of first use, contributed to the highest furfural gains. The furfural content in the different barrels varied between 0.63 and 1.83 mg/100 mL of anhydrous alcohol, depending on the type of wood. The antioxidant potential was assessed by means of DPPH decolorization in the alcoholic and aqueous extracts. For the alcoholic extracts, discoloration ranged from 3.19% to 27.02%, with the balsam barrels showing the highest final values. In the aqueous extracts, the values ranged from 0.00% to 1.59%, again with balsam standing out as the wood that provided the greatest antioxidant potential. The results indicate that the type of wood used to age cachaça directly influences its chemical profile and antioxidant properties, with balsam barrels standing out in both respects.

(2025) Cabral, Daniel Velloso; Briceno, Julio Cesar Colivet; Cardoso, Claudio Fernandes; Silva Filho, Roberto Braz da; Sousa, Luciana Aparecida de; Oliveira, Tatianne Ferreira de; Silva, Flavio Alves da
Coffee is one of the world’s main commodities, with Brazil being the largest producer. When it meets production and sensory quality requirements, coffee can be classified as a specialty by the Brazilian Coffee Industry Association or Specialty Coffee Association, being recognized for its aroma and taste, defined by volatile and non-volatile organic compounds, as well as the benefits such as antioxidant activity, which can vary according to the cultivation region. This study evaluates the influence of different planting locations on volatiles, color, phenolics, and antioxidant activity in Arabica coffee (Catuaí cultivar) from five Brazilian regions. The coffees were roasted uniformly, analyzed by gas chromatography-mass spectrometry for volatiles, colorimeter for color, and liquid-solid extraction for phenolics (Folin-Ciocalteu) and antioxidant activity [2,2’-azinobis-(3-ethylbenzthiazolin-6-sulfonic acid), 2,2-diphenyl-1-picrylhydrazyl, and ferric reducing antioxidant power]. The data was treated using Analysis of variance and Tukey’s test, as well as boxplot, principal component analysis, and heatmap. The colors varied significantly between the regions. Twenty-seven volatiles were common to the 5 regions, with distinct sensory contributions such as pyridine and acetic acid in coffee from the Rio Paranaíba region, and 1-methylpyrrole for the other regions. For phenolic and antioxidant content, coffee from the Rio Paranaíba region had the highest values. It was possible to see a distinction between the coffees by planting location.

(2025) Peres, Daiane Sousa; Santos, Priscila Alonso dos; Pilon, Lucimeire; Miranda, Bruna Melo; Santos, Cleberly Evangelista dos; Silva, Flávio Alves da
The objective of this study is to provide a comprehensive comparison of five underexplored Brazilian Capsicum cultivars, Maria Bonita (MB), Dedo-de-moça (DM), Bode (BD), Malagueta (ML), and Habanero (HB), and highlight their distinct nutritional and bioactive profiles. It was to evaluate the physicochemical, bioactive, volatile, mineral and capsaicinoid qualities of the five different peppers. Maria Bonita, Bode and Habanero present different morphological and physicochemical characteristics due to genetic diversity. The cultivar DM presented the lowest value of L* (35.32) and chromaticity (41.52), indicating a darker color. The ML pepper obtained the lowest value of water content (70.43 g/100 g), consequently obtaining better results in the centesimal composition. The highest carotenoid contents were found for DM (1857.36 μg/g), BD (769.67 μg/g) and HB (774.49 μg/g) respectively. The cultivars differed significantly in terms of macrominerals and microminerals. Capsaicinoid levels did not differ for ML (120,403.69 SHU) and HB (128,086.00 SHU). The cultivars bode, malagueta and habanero stood out, presenting higher levels of bioactives, indicating a high potential for these peppers in functional foods and value-added applications, such as pharmaceutical and biotechnological.
Activated carbons from Baru (Dipteryx alata Vog.) waste impregnated with copper oxide: application in the postharvest preservation of bananas
(2025) Oliveira, Ana Carolina de Jesus; Silva, Flávio Alves da; Oliveira, Tatianne Ferreira de; Valdés, Héctor
Banana is an agricultural commodity cultivated extensively in tropical and subtropical regions with consumption demand worldwide. During the ripening process, several biochemical reactions occur that are linked to the production of ethylene, which determines the shelf life and quality of the fruit. Ethylene can promote excessive ripening and decay of fruits and vegetables, even at very low concentrations. Therefore, an ethylene control strategy needs to be developed to address this challenge. This study aimed to evaluate the effects of using activated carbon from baru (Dipteryx alata Vog.) waste, impregnated with copper oxide, as potentially efficient materials for eliminating ethylene and maintaining postharvest quality of bananas. The developed adsorbent materials showed high ethylene adsorption capacity, validating their potential application in real storage conditions for climacteric fruits. The evaluation of quality attributes, like color, firmness, weight loss, total titratable acidity, total soluble solids, and total soluble solids/total titratable acidity ratio, confirmed the effectiveness of activated carbon and activated carbon impregnated with copper oxide in delaying the ripening and senescence process compared to bananas in the control group. The results of this study contribute to the development of ethylene adsorbent materials that combine sustainability and efficiency, with promising applications in the food industry to reduce postharvest losses.
Kinetics of volatile aromatic compound production during the aging of cachaça in different types of wood
(2025) Briceno, Julio Cesar Colivet; Rabelo, Paula Novais; Belo, Lúcio; Mendes, Dianiny de Cássia Sousa; Caliari, Márcio; Silva, Flavio Alves da; Morgado, Cristiane Maria Ascari; Oliveira, Tatianne Ferreira de
This study evaluated cachaças aged up to 48 months in four types of wood (oak, amburana, balsam, and chestnut), with analyses performed every four months, totaling 48 samples per type of wood. Compounds such as ethyl acetate, ethyl lactate, and aldehydes were identified and quantified by gas chromatography and were kinetically modeled by the Peleg model. The results demonstrated that the model presented an excellent fit to the experimental data (R² > 0.94), indicating that the production of volatile compounds follows second-order kinetics. The initial production rate was higher in the first 24 months, with stabilization observed after this period. Tropical woods, like amburana, balsam, oak, and chestnut, presented a higher initial production rate than oak, demonstrating a slower but constant evolution throughout aging. Light and volatile compounds, such as acetaldehyde and ethyl acetate, predominated initially, contributing to fresh and fruity aromatic profiles. Compounds with a higher molecular weight, as ethyl palmitate and phenols, became more evident in the final stages and were associated with denser and more complex sensory notes. This study highlights the significant impact of wood type and aging time on the chemical and sensory profile of cachaça, providing valuable information for optimizing the aging process and developing beverages with unique aromatic characteristics.
Animal-derived proteins as stabilizers of Pickering emulsions: applications and challenges
(2025) Souza, Ana Carla Aguiar de; Briceno, Julio Cesar Colivet; Trindade, Dennia Pires de Amorim; Conceição, Edemilson Cardoso da; Oliveira, Tatianne Ferreira de; Gómez-Estaca, Joaquín; Silva, Flavio Alves da
Emulsions are precursors for formulating stable food products with high demand worldwide and efficient cosmetics that can provide the capability of delivering bioavailable active ingredients. The development of Pickering emulsions is crucial because they can eliminate the more prolonged need for chemical stabilizers, increasing the sustainability and stability of the formulation. Conventional emulsion formulations employ chemical surfactants to stabilize. Nevertheless, incorporating proteins as emulsion stabilizers improves stability and attractiveness. Therefore, a systematic reference review is essential to give theoretical knowledge of Pickering emulsions and their structures and properties to review critical aspects, the mechanisms, and the vital applications to promote their stability. The subject of this review article is research focused on developing new protein modification technologies, improving their properties, and extending their applications. The applications of casein, whey protein, and egg albumin as emulsion stabilizers primarily focus on widely published literature. The present study focuses on evaluating the food industrial applications of casein, whey protein, egg albumin, lactoferrin, and myofibrils. The bioavailability of casein, whey protein, and egg albumin is essential for applying in Pickering emulsion, and it can be a limiting factor. We are opening new opportunities and options for utilizing alternative proteins, such as emulsion stabilizers.
The science of aging: understanding phenolic and flavor compounds and their influence on alcoholic beverages aged with alternative woods
(2025) Souza, Tainá Francisca Cordeiro de; Miranda, Bruna Melo; Briceno, Julio Cesar Colivet; Gómez-Estaca, Joaquín; Silva, Flávio Alves da
Aging in wooden barrels is a proven technique that enhances the sensory complexity of alcoholic beverages by promoting the extraction of volatile and phenolic compounds. While oak has been traditionally used, there is a growing interest in exploring alternative wood species that can impart distinct sensory characteristics and promote innovative maturation processes. This review examines the impact of alternative woods on the aging of beverages, such as wine, cachaça, tequila, and beer, focusing on their influence on aroma, flavor, color, and chemical composition. A bibliometric analysis highlights the increasing scientific attention toward wood diversification and emerging aging technologies, including ultrasound and micro-oxygenation, which accelerate maturation while preserving sensory complexity. The role of toasting techniques in modulating the release of phenolic and volatile compounds is also discussed, emphasizing their contribution to unique sensory profiles. Additionally, regulatory aspects and sustainability considerations are explored, suggesting that alternative woods can expand flavor possibilities while supporting environmentally sustainable practices. This review underscores the potential of non-traditional wood species to drive innovation in the aging of alcoholic beverages and provide new sensory experiences that align with evolving consumer preferences and market trends.
Effects of thiamethoxam insecticide on sugarcane plant growth under chemical ripening at early and late harvest
(2025-07) Silva, Deise de Paula; Oliveira, Josiane Aparecida Viveiros de; Jacomassi, Lucas Moraes; Oliveira, Marcela Pacola; Marques, Letusa Momesso; Siqueira, Gabriela Ferraz de; Martello, Jorge Martinelli; Foltran, Rodrigo; Soratto, Rogério Peres; Dinardo-Miranda, Leila Luci
Chemical ripeners are applied to ensure the quality of the final product in sugarcane production, especially under unfavorable conditions for sucrose accumulation. In addition, bioactivators such as the insecticide thiamethoxam can stimulate plant development. Thus, the application of thiamethoxam to sugarcane regrowth associated with ripener may have phytotonic effects and improve sugarcane quality and yield. The aim of this study was to understand the effects of thiamethoxam foliar application to sugarcane ratoon treated with trinexapacethyl as a ripener. Four management strategies (treatments) were introduced and tested in six field experiments conducted across the early and late harvest seasons: no chemical application (control), application of 250 g a.i ha-1 trinexapac-ethyl (0.4 Lha-1 of commercial product) as a ripener, application of thiamethoxam 100 g a.i ha-1 (0.4 kg ha-1 of commercial product) as a bioactivator, and application of ripener and bioactivator. Thiamethoxam application increased stalk yield by 14 Mg ha-1 compared with the control, and joint application with ripener increased sugar yield by up to 3 Mg ha-1 due to an increase in total recoverable sugar (TRS) of up to 11% compared with the control (139.9 kg Mg-1). The increases in biomass in response to thiamethoxam application increased potential energy production (MWh) by 16.8% compared with the treatments without insecticide. The integration of thiamethoxam into sugarcane management enhanced yield, biomass, and energy-related traits without compromising technological quality. When combined with trinexapac-ethyl, it increased sugar yield per hectare. These benefits point to improved land-use efficiency. However, given its classification as a neonicotinoid, further studies are needed to assess long-term safety. Such research is key to aligning productivity with sustainability in sugarcane systems.
Enhancing cherry tomato performance under water deficit through microbial inoculation with Bacillus subtilis and Burkholderia seminalis
(2025) Oliveira, Henrique Fonseca Elias de; Silva, Thiago Dias; Silva, Jhon Lennon Bezerra da; Selaria, Priscila Jane Romano Gonçalves; Silva, Marcos Vinícius da; Mesquita, Marcio; Silva, Josef Augusto Oberdan Souza; Ferrarezi, Rhuanito Soranz
Crop productivity can be affected by biotic and abiotic stressors, and plant growth promoting bacteria (PGPB) from the genera Bacillus and Burkholderia have the potential to maintain fruit yield and quality, as these bacteria can promote plant growth by solubilizing nutrients, fixing atmospheric nitrogen, producing phytohormones, and exhibiting antagonistic activity against pathogens. This study aimed to evaluate the effects of inoculating plants with Bacillus subtilis and Burkholderia seminalis on their morphological characteristics, fruit technological attributes and yield of common cherry tomatoes (Solanum lycopersicum L.) subjected to induced water deficit. The study was arranged on a split-plot randomized block design, with four water replacement levels (40%, 60%, 80% and 100% of crop evapotranspiration, ETc) and three inoculation treatments (Bacillus subtilis ATCC 23858, Burkholderia seminalis TC3.4.2R3 and non-inoculation). Data were subjected to analysis of variance using the F-test and compared using Tukey’s test (p < 0.05) and multivariate statistics from principal component analysis. Inoculation with Burkholderia seminalis increased the plant fresh and dry shoot and root mass, as well as root volume. Inoculation with Bacillus subtilis increased carotenoid and chlorophyll b contents. Both inoculations enhanced leaf water content in plants experiencing severe water deficit (40% of ETc). The use of these strains as PGPB increased the fruit soluble solids content. Higher productivity in inoculated plants was achieved through a greater number of fruits per cluster, despite the individual fruits being lighter. Treatments with higher water replacement levels resulted in greater yield. Inoculations showed biotechnological potential in mitigating water deficit in cherry tomatoes.
