Alleviation of Salt Stress in Cucumis Sativus L. Through Seed Priming with Calcium Chloride

Neelu Joshi, Amita Jain, Karan Arya

Abstract :

The present study was aimed at evaluating the potential of calcium chloride in inducing salt tolerance in Cucumis sativus L. at germination and early seedling growth stage. Response of C.sativus seeds to the pre–soaking (priming) treatment with 2 mM CaCl2 solution for 24 h was studied under saline condition (100mM and 150mM NaCl). Exogenous CaCl2 significantly ameliorated the detrimental effects of NaCl stress on germination and seedling growth. Germination potential increased by 12% in primed seeds as compared to non–primed seeds under saline condition. Shoot and root lengths of primed seedlings were two times higher than non–primed seedlings. Influence of CaCl2  priming on phenol and proline content and antioxidative enzyme activities was also studied and all these parameters were found to be significantly higher in primed seedlings as compared to non–primed seedlings. These findings suggested that the beneficial effects of CaCl2 priming on germination and seedling growth could be due to its role in activation of antioxidant system and accumulation of proline
