Morphological characterization of fruit, seed and seedling and germination of Hymenaea courbaril L. (Fabaceae) ('Jatobá')
Abstract This study has aimed to characterize the morphology of fruit, seed and seedling and evaluate the germination of Hymenaea courbaril L., under different substrates and temperatures. The physical characteristics were determined, as well as the morphological description of the internal and external parts of fruits and seeds, stages of germination and early seedling development. Germination tests were conducted in a completely randomized design, in a 3x2 factorial scheme, with three temperatures (20 °C, 25 °C and 30 °C) and two substrates (sand and vermiculite), with six plots of 30 seeds. The germination percentage, germination speed index (GSI) and mean germination time (MGT) were calculated. The fruits are dry and woody and the seeds are exalbuminous, with an axial embryo. The germination is epigeal and the seedling is phanerocotylar. The combination of vermiculite or sand associated to temperatures of 25 °C or 30 °C is effective for conducting the germination tests.
