Effects of abscisic acid and sodium nitroprusside priming on yield and quality of peanut (Arachis hypogaea L.) under drought stress

Abstract

This study tested the impact of priming peanut seeds from the VD01-2 cultivar with either 6 mg/L of abscisic acid or 20 mg/L of sodium nitroprusside to prevent damage from drought stress. Throughout the development of peanuts under drought-stress conditions, various morphological, physiological, and biochemical changes were analyzed. According to the study, it was determined that priming with SNP had a more significant effect than priming with ABA. The use of sodium nitroprusside priming resulted in an improvement in both the yield and quality of peanuts when grown under drought conditions. Furthermore, the findings indicate that the use of sodium nitroprusside priming showed an increase in chlorophyll content, gas exchange capacity, and antioxidant activities while reducing lipid peroxidation.
