Exogenous putrescine and calcium nitrate alleviate water deficit stress in sesamum indicum L. by modulating antioxidant defense and nutrient homeostasis
Water deficit is a major constraint for sesame (Sesamum indicum L.) production in arid and semi-arid regions. This study evaluated the effects of foliar application of calcium nitrate )Ca(NO₃)₂; 0, 5, and 10 mM( and putrescine (Put; 0 and 0.5 mM) on the physiological and biochemical responses of sesame under three irri...
