【 摘 要 】

Hymenaeastigonocarpa(Mart.ExHayne),popularlyknownasjatobá-do-cerrado,isafruittreewidelydistributedin the Brazilian Savanna, has multiple uses and is a promising geneticresource.Thisstudyaimedtophysicallycharacterizefruits and seeds of H. stigonocarpa, as well as to estimate the phenotypic variability at three hierarchical levels: populations, mother trees within populations, and fruits/seeds within mother trees.Fruitsfromsixmothertreesweresampledfromeachofthe25naturalpopulationsfoundintheBrazilianSavanna.Themorphometriccharacterizationof742fruitswascarriedoutbyevaluating10quantitativetraitsinfruitsandseeds.Inaddition,comparativeanalyseswereperformedbetweentheaveragevaluesofH.stigonocarpaandthebotanicalvarietyH.stigonocarpavar.brevipetiolata. Significant phenotypic variationswerenoticedatallhierarchicallevels.Ahighphenotypic differentiation among the populations was observed for quantitative traits (fruit mass and size, pulp mass and seed mass), being higher when H. stigonocarpa var. brevipetiolata was included in the analysis.
