Synergistic effect of nitric oxide and arginine on stress markers and yield attributes of B. napus grown in salt stress. (A) Malondialdehyde (MDA), (B) Hydrogen peroxide (H2O2), (C) Relative membrane permeability (RMP) and (D) Relative water content (RWC). Graph bars presented mean of three replicates ± standard errors in error bars. Different alphabets above graph bars obtained after Duncan’s multiple range test presented mean values are significantly different at p ≤ 0.05.
