Morphological Studies of the Euterpe oleracea Mart. Seeds

The aim of this research is to describe the morpho-anatomy of Euterpe oleracea Mart. seed. The samples with 30 seeds (0, 10, 30 days after the beginning of the germination process), in which the seeds were placed in plastic boxes with sand as substrate and immediately introduced in germination chamber under 30 °C, being irrigated daily with distilled water. The morphological and anatomical observations of the seed were carried out in the times 0, 10 and 30 and 0 days of germination, respectively. This seed has ruminated endosperm, solid, besides being constituted by large cellular walls, with several pit primary fields. The testa is ruminated, constituted by fine cellular walls, divided in three layers (external, medium and internal), it being that the medium layer has vascular bundles. The embryo is conic, basal and axial linear, with two regions, being a proximal (hypocotyl-radicle axis) and other distal (cotyledon).
