ABSTRACT

In the present study, we evaluated the effects of osmotic conditioning (priming) on seed germination and emergence rate index (ERI) of Panicum coloratum cv Klein Green, under optimal germination conditions (watered with distilled water) and salt stress (irrigated with different water potentials of NaCl solution). The seeds were primed in 3 osmotic solutions (NaCl, KCl, and K2SO4) during 2 days at 15°C. After the treatments the seed was germinated in 3 levels of salinity/osmotic potential media (12 μscm-1/-0,5 MPa; 30 μscm-1/-1,0 MPa; 43 μscm-1/-1,5 MPa). Salt stress conditions generate a depressive effect on the speed and germination percentage of Panicum coloratum seeds. Priming treatments increase significantly the germination percentage and ERI in prime seeds compared to untreated in non saline condition. At 12 μscm-1/-0,5 MPa salinity levels, the primed seeds showed higher significantly germination velocity (ERI) compared with non primed seeds.
