Involvement of Ethylene in Reversal of Salt Stress by Salicylic Acid in the Presence of Sulfur in Mustard (Brassica juncea L.)

The involvement of ethylene in reversal salt (NaCl; 50 mM) stress on photosynthetic activity and growth by salicylic acid (SA; 0.5 together with sulfur (S; 2.0 was studied mustard (Brassica juncea L. cv. Pusa Vijay). Application SA plus SO42? improved through markedly increased S-assimilation, strengthening antioxidant defense system limiting NaCl-accrued oxidative consequences more conspicuously than their individual effect B. under mM NaCl stress. Since acts as an inhibitor S-assimilation is associated synthesis, we tried to figure out the interaction SO42?-mediated tolerance. supplementing salt-treated plants 200 µL L?1 ethephon (an ethylene-releasing compound) or 100 µM norbornadiene (NBD, action inhibitor) treatments. Ethephon supplemented NaCl-treated showed optimal formation, increasing sensitivity enhance photosynthesis affecting antioxidative capacity plants. treatment decreased production optimized formation that contributed maintenance high rate, which reversed NBD. receiving NBD inhibited characteristics growth, minimal capacity, enzymes GSH content. This involvement. Overall, intervened presence induce upregulated enzymatic non-enzymatic antioxidants, imparted tolerance
