Morphology of the fruit, the seed and the seedlings of chestnut tree (Terminalia catappa L. - COMBRETACEAE). Rev. Bras. Frutic. [online]. 2008, vol.30, n.2, pp.517-522.

The work was carried out with the objective of describing morphologically the fruits, seeds and seedlings of chestnut tree. It was made the biometry of the fruits and seeds with a digital pachymeter and its characterization in relation to the shape, in stereomicroscope with clear chamber. It can be evidenced that the chestnut tree fruits are fleshly, indehiscent, nucoid, glabrous, from green to purple coloration, with evident projection of the carpel ribbings, with a fleshly and spongy epicarp and mesocarp, of purple color, with conspicuous vascular bundle in transversal cut. Generally, it has a seed per fruit. The seeds are unalbuminous, of prolongated and cylindrical shape and recovered with a rigid endocarp of brown coloration. The seeds possess about 2,5; 0,7 and 0,7 cm, of length, width and thickness, respectively. The germination of the seeds of chestnut tree is epigeal and the seedling is fanerocotyledonary.
