Activity of 1-aminocyclopropane carboxylic acid (ACC) synthase (ACS) and ethylene evolution in mustard (Brassica juncea L.) cv Pusa Jai Kisan at 30 DAS. Plants were grown with 100 mM NaCl (S) or 10 mM N plus 200 µl l⁻¹ ethephon (10 N + 200E) individually or in combination, and the plants grown with 10 N + 200 E alone or with NaCl (S) were treated with 100 µM norbornadiene (NBD). Data represent mean values ± SE (n = 4). Means denoted by the same letter are not significantly different at P < 0.05.
