Effect of ascorbic acid (AsA) on glycine betaine, total free proline, anthocyanin, ascorbic acid and total phenolics of pea under salt stress. The three replicates ± SE is shown by the error bars above the means. For a parameter, means that share same letters do not differ significantly at p < 0.05. (V1 = Meteor; V2 = Sarsabz; T0 = Control + 0 mM AsA, T1 = Control + 5 mM AsA, T2 = Control + 10 mM AsA, T3 = 100 mM NaCl + 0 mM AsA, T4 = 100 mM NaCl + 5 mM AsA and T5 = 100 mM NaCl + 10 mM AsA)
