Resumo
It has many uses, especially food, medical, timber, ornamental and reforestation. Its fruits can be eaten raw or processed for the preparation of juices, liquors, cakes, ice cream. However, their exploitation has been made of extraction form and often predatory. There needs to be rational and economically viable farm, for it is necessary to carry out the domestication of the species, basic information on their phenology and growth, allowing its cultivation in a sustainable manner. The objective of this research was to evaluate the phenology, biometrics and survival of a collection of cagaiteiras in early stages of implemented development at the College of Agriculture / Federal University of Goiás. For that collection were collected ripe fruit of twenty-five natural subpopulations in the Cerrado, in five Brazilian states (Bahia, Goiás, Mato Grosso, Minas Gerais and Tocantins). Within each subpopulation six trees (matrices) were sampled (with exceptions in subpopulations 2, 12 and 21 with 5, 4 and 5 arrays, respectively), and fruits (mother's brothers) of each array were collected. The population consisted of 146 families of maternal brothers. The experimental design was a randomized complete block design and three replicates, performing analysis of variance (F test) and the averages compared by Scott-Knott test at 5%. The collection was established in November 2013, evaluations occurred between April and October 2014. We conducted an initial assessment and other monthly between April and October 2014. The coefficients of variation (CVs) were 33.59% and 49.23% for stem diameter, and total plant height, respectively. The means of stem diameters between progenies ranged from 1.08 mm (m2p15 - Dois Irmãos, GO) to 4.13 mm (m2p4 - Coromandel, MG). For total plant height averages ranged from 3.54 cm (m3p16 - Niquelândia, GO) to 32.67 cm (m2p4 - Coromandel, MG), the highlight was the m2p4 (Coromandel - MG), which was obtained higher averages for the two variables evaluated. In September the cagaiteiras showed an increase in the emergence of new leaves and in October intensified. There was a high survival for all tested subpopulations,> 60% between 72.22% and 100%. Increase in level, the plants of the subpopulation 14 (Mimoso - GO) had both higher average paras variables stem diameter and total plant height, 2.88 mm and 11.39 cm, respectively.
