Effect of salicylic acid treatments on the a nitrate reductase, b proline and c lipid peroxidation levels in the leaves of B. carinata cultivars grown under salt stress (where T1 = control; T2 = 0 mM NaCl with 0.5 mM SA; T3 = 50 mM NaCl without SA; T4 = 50 mM NaCl with 0.5 mM SA; T5 = 100 mM NaCl without SA; T6 = 100 mM NaCl with 0.5 mM SA; T7 = 150 mM NaCl without SA; and T8 = 150 mM NaCl with 0.5 mM SA). Each value represents the mean ± SE of five replicates
