Biometry and maturation of Sesbania punicea (Cav.) Benth. seeds

The objective of the study was to evaluate biometry fruits and seeds S. punicea in order determine point collection for production seedlings species. were collected from plants situ Barra do Ribeiro, RS. In laboratory, they separated by staining in: stage 1, 2 3. Fruits measured with digital caliper (mm), counting number locules. At each water content, seed dry matter germination test evaluated. For this last one, four replications 25 placed chamber during 16 days, photoperiod 12 hours temperature 25ºC. variables analyzed germination, speed index, average time, percentage normal abnormal seedlings, hard seeds. It observed that have larger dimensions, a higher formation rate speed. is concluded must be harvested at maturation, as highest rates well lowest insect damage.
