Abstract

This study evaluated the effect of the osmopriming on germination and vigour of Sesbania virgata seeds. Seeds were chemically scarified in concentrated sulphuric acid for 40 minutes and put to germinate either directly or after being submitted to osmopriming, drying and accelerated aging. Osmopriming was carried out with polyethylene glycol solutions (PEG 8000) at the following osmotic potentials-0.2; -0.4; -0.6 and -0.8 MPa for 12, 24 and 48 hours. After osmopriming, seeds were dried in silica gel until the initial moisture content was reached, and then submitted to the accelerated aging (48 h/100% RH). The effects of osmopriming and accelerated aging were evaluated through germination test, first counting germination and germination speed index. The osmopriming, followed or not by accelerated aging, positively influenced germination and vigour of Sesbania virgata seeds.
