Aspectos morfo-anatômicos de sementes de Podocarpus lambertii Klotz. e Podocarpus sellowii Klotz. - Podocarpaceae

Abstract

Seed and fruit development studies are essential for comprehension of forest species performance. The aim of these studies was to follow the complete development and dispersal of Podocarpus lambertii Klotz. and Podocarpus sellowii Klotz. seeds. Fortnightly collections in the selected areas were made from the start of bract formation to seed ripeness. Materials collected were analyzed under photonic and stereoscopic microscopy. Female strobilus consist of seed and epimatium, fixed on a thin peduncle. The seeds are globe-shaped, with tegment consiting of three cellular layers. The endosperm of the seeds is abundant and of gelatine consistency. The embryo of both species is linear and cotyledonous.
