Fig. 2.

Response of antioxidant defense pathway with different treatments in experiment I (a–g) and experiment II (h–n). CAT activity, µmol min⁻¹ mg⁻¹ protein (a, h); AsA content, µmol g⁻¹ FW (b, i); APX activity, nmol min⁻¹ mg⁻¹ protein (c, j); MDHAR activity, nmol min⁻¹ mg⁻¹ protein (d, k); DHAR activity, nmol min⁻¹ mg⁻¹ protein (e, l); GR activity, nmol min⁻¹ mg⁻¹ protein (f, m); and GSH content, µmol g⁻¹ FW (g, n). Treatments are the same as described in Table 1. Mean (± SD) were calculated from three replicates for each treatment. Values with different letters are significantly different at P ≤ 0.05 applying Fisher’s LSD test
