Effects of melatonin on the growth of wheat seedlings grown under control and salt stress (100 mM NaCl) conditions for 16 days. (A) Biomass of wheat seedlings pretreated with and without melatonin (1 μM) under salt stress (100 mM NaCl). (B) IAA concentrations of wheat seedlings pretreated with and without melatonin under salt stress. Data represent the mean ± SE of three biological repeats, and different lowercase letters above the bars indicating significant differences according to Duncan’s multiple range tests (P < 0.05), the upper error bar refers to shoot variation.
