Abstract

Abstract : Salinity is one of the most important abiotic stresses that affect vegetative growth, reproductive yield, biomass distribution, and physiological parameters of many crop plants. A study was conducted to evaluate these parameters in soybean plants (cv. Peking and LS678), following seed priming with benzyladenine (2.16 µ M). Soybean plants were subjected to salinity stress imposed by irrigation with a high amount of NaCl (250 mM) solution under greenhouse conditions. Results showed that exogenously applied benzyladenine dramatically improved growth, biomass, and yield parameters as a priming solution compared to hydroprimed plants exposed to similar salt stress conditions. High reduction in mean photosynthetic pigments (0.87–1.88), carbohydrates (24.942–27.091%), phenolic content (2.28–2.33), flavonoids (2.37–2.11), and antioxidant capacity (34.5–37.2%) was observed in plants developed from hydroprimed seeds under salt conditions. These findings suggest that priming of seeds with 2.16 µ M benzyladenine improved the vegetative, reproductive, and physiological responses of soybeans under induced salinity stress.
