FIGURE 3

Effects of NO on activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR) in leaves of chickpea plants under salt stress. Data presented are the means ± SEs (n = 5). Different letters indicate significant difference (P ≤ 0.05) among the treatments. T0 (control) = 0 mM NaCl + 0 μM SNAP; T1 = 0 mM NaCl + 50 μM SNAP; T2 = 50 mM NaCl + 0 μM SNAP; T3 = 50 mM NaCl + 50 μM SNAP; T4 = 100 mM NaCl + 0 μM SNAP; T5 = 100 mM NaCl + 50 μM SNAP. EU, enzyme unit.
