Effect of individual and combined application of IAA and compost on (A) Malondialdehyde contents (MDA; n mol mint− 1 mg− 1 protein), (B) Hydrogen peroxide (H2O2; µmol g− 1 FW), (C) Proline contents (µmol g− 1 fresh weight), (D) Electrolyte Leakage (EL; %) under Ni stress. Bars displaying same alphabets are statistically non-significant at P < 0.05
