Abstract

Effect of salinity on emergence, seedling growth and seed vigor of Oenothera biennis L., a medicinal plant was considered using different concentrations of NaCl (25 mM, 50 mM, 75 mM and 100 mM). Increasing stress regimes upto50 mM led to enhancement of seed germination. At higher salt concentrations a negative relationship between seed germination was obtained. Seedling survived and grew up to salinity of 100 mM NaCl and eventually this species is tolerant to seedling stage. Elongation of stem and root was decelerated by increasing salt stress. Though, this species has a tendency for rapid root penetration and roots are able to draw water from saline soil. Seed vigor index decreased with increasing concentration of stress.
