Diferenças fenológicas e produtivas de variedades de mangaba

Abstract

He mangabeira is a species with potential for domestication and commercial production, but the great variation found in native plants requires greater knowledge to direct its use and exploration. In this context, this study seeks to analyze the varieties of Hancornia speciosa from a germplasm bank, regarding the characteristics of phenology, fruits, seeds and initial development. The research was carried out in 2018, at the Germplasm Bank of the School of Agronomy of the Federal University of Goiás, with progenies of 28 native populations, aged 14, covering the subspecies pubescens, gardneri, speciosa and cuyabensis. The analyzed data were of phenology, characterizing the foliage, flowering, new shoots and fruiting. Characterization of fruits and seeds, in addition to the initial development of seedlings. Flowering was the stage of greatest differentiation between varieties, being the speciosa with the highest flowering in the period. The varieties cuyabensis and gardneri showed to be close phenologically while the pubescens showed absence of flowering and fruiting in the period. The cuyabensis and gardneri varieties were also close in terms of fruit and seed characterization, while speciosa was the most distant. The latter showed a larger diameter of fruits, in addition to a greater number and mass of seeds. As for the mass of fruits, the varieties cuyabensis and gardneri were superior. The initial development was different only for speciosa, which presented greater height, diameter and number of leaf pairs.
