Abstract

Salinity stress inhibits plant growth by affecting morphological, photosynthesis, antioxidant phenomena, and nitrogen metabolism, among other physiological and biochemical processes. In this study, the effects of pre-soaking Wheat and Mung grains in aqueous extract of Cissus quadrangularis on growth, and antioxidant activity of salt-treated plants, were investigated. The pre-soaking of grains in extract demonstrated a significant enhancement in growth parameters. The activity of superoxide dismutase (SOD), guaiacol peroxidise (GPOX), and ascorbate peroxidase (APX), catalase (CAT) increased with increasing the concentration of C. quadrangularis extract up to 3%w/v while decreasing when at a higher concentration of 10%w/v. The estimation of bioactive compound Proline also observes higher concentrations at 3%w/v under treatment with different salt stress. Therefore, the study suggested that seed priming with plant extract is an effective technique to improve the growth of Wheat and Mung seedlings under salt stress conditions.
