ARLEM NASCIMENTO DE OLIVEIRA, MARIA SILVIA DE MENDONÇA QUEIROZ E MICHELE BRAULE PINTO RAMOS
The different Amazon ecosystems condition a wide adaptation of the vegetable species. Tephrosia candida DC. is an exotic legume, root nodule, with potential for use agroforestry in the area. The study was accomplished in laboratory conditions in the ability of Agrarian Sciences (UA), being worked with fruits and seeds of T. candida, seeking to supply morphologic data as subsidies for future taxonomics and ecological studies of the species. The fruit of T. candida is a vegetable, of not very thick and dry pericarp, whose coloration varied of brown-clearing to the brown-darkness, presenting nine seeds on the average for fruit. The seed is campylotropous, reniform, being the wrapping dicromic and with a cartaceous covering. The embryo is invaginad and papilionaceous type with embryonic axis curved, falsiform and pleurorrize. The plumule is rudimentary and of yellowish coloration. The cotyledons are elipsoidal, of fleshy consistency and split apex, with an exposed radicle, whose chemical analyses gave positive answers for protein, starch and tannin, being the two first the main types of reservations of the seed.
