Table 1.
Content of leaf Na+ (mg g−1 DW), Cl− (mg g−1 DW), H2O2 (nmol g −1 FW) and thiobarbituric acid reactive substances (TBARS, nmol g−1 FW) in mustard (Brassica juncea L.) cv Pusa Jai Kisan at 30 DAS. Plants were treated either with 5 mM N, 10 mM N, 200 µl l−1 ethephon in different combinations and grown with or without 100 mM NaCl. Data means with the same letter are not different significantly at P < 0.05. DW, dry weight; FW, fresh weight.
