Morfologia de frutos e sementes de espécies arbóreas do gênero Solanum L.

Abstract

The aim of this study was to characterize the fruit and seed morphology of three Brazilian forest species, Solanum granuloso-leprosum Dunal, S. lycocarpum A.St.-Hil. and S. pseudoquina A.St.-Hil., recommended for plantations of degraded area recovery. The fruits are indehiscent, fleshy, berry type, globouse, polispermic and consist of two or more loculus. The seeds are stenospermics, campylotropous, elliptics, compressed, presenting broad-ovate or flattened-ovate longitudinal section and elliptical transversal section. Hilum medioum-marginal situated in a depression; rounded micropyle. Seeds albuminous, with abundant endosperm, peripherical, fleshy-firm, semitransparent and of white coloration. Axile, linear, continuous and curved embryo. Solanum lycocarpum and S. pseudoquina present circinate embryo and S. granuloso-leprosum spirally embryo.
