بررسي تاثير شوري برجوانه زني بذر و رشد گياهچه در شش گونه گياه دارويي

The effect of salinity on seed germination and growth in six medicinal plants.

This study was conducted to evaluate salt tolerance in Cyamopsis psoraloides, Cynara scolymus, Hibiscus sabdariffa, Cassia angustifolia, Ocimum basilicum and Hyssopus officinalis at germination stage. Salinity levels, including 0, 50, 100, and 200 mM were applied using a completely randomized design with three replications. Germination percentage and rate were measured in the Petri dishes and root and shoot lengths were recorded at seeding stage. There was no germination for Hibiscus sabdariffa, Cassia angustifolia, Ocimum basilicum and Hyssopus officinalis at 200 mM NaCl. However, Cyamopsis psoraloides and Cynara scolymus showed seed germination at 200 mM NaCl. Higher salt tolerance potential in some species makes cultivation possible or other stress tolerant medicinal plants under saline environments.
