Biometry end morphology of seed end seedling of oiticica

Lack of works in native plants of caatinga northeastern is obvious, especially, relating to study of seeds. Among these species, stands out for its multiple uses, the oiticica (Licania rigida Benth). The objective of present experiment was to determinate the biometry and morphology the seed end seedling of Licania rigida. The essay was conducted at the Laboratory of Analysis of Seeds of the Phytotechny Department/UFC. Used were what measurement referent this length, width end thickness as well as detailed description internal end external of seed. Results showed that the seeds are euryspermycs, has length 3.1 to 5.0 cm, width 1.3 to 1.7 cm and thickness 1.2 to 1.7 cm. The embryo is large linear format, with fleshy cotyledons yellowed, folded white and have short ribs and the hypocotyl-radicle axis. Germination starts after 15 days, hypogeal cryptocotylar. The seedling has the faces of the leaf primordia, a whitish layer cotonoso aspect.
