The Brazil nut tree (Bertholletia excelsa Bonpl.), one of the main species from the socioeconomic and ecological point of view of the Amazon, is characterized by slow and uneven germination. Considering that its genetic constitution is a determining factor for the morphology and physiology of germination, we investigated different Brazil nut tree genotypes regarding morphophysiological seed traits and performed a morphoanatomical description of the leaves. Genotypes showed differences in seed morphology, imbibition curve, germination rate, and germination speed index, and also, in some of the morphoanatomical leaf structures. The genotype 606 showed the best physiological performance during germination, mainly in terms of water imbibition, as it needs to absorb less water and achieve a higher germination percentage than the genotype Sant Fé, in addition to a higher stomatal index. In the evaluated genotypes, quintenary venation was observed in the leaves, different from a leaf from a wild matrix. Our findings aid the morphoanatomical differentiation of different genotypes of B. excelsa, and represent a significant step forward for clonal propagation, as well as providing a route for improving these species’ physiological and genetic characteristics. |
