Effects of different melatonin and ABA concentrations on fresh weight (a,c) and electrolyte leakage (b,d) in DX and GN seedlings under cold stress (4 °C). Plants treated with distilled water under the normal conditions (25 °C) served as controls. Each value represents the mean of three replicates ± SD, and different letters above the bars indicate significant differences at P < 0.05 among different treatments in the same genotype according to Duncan’s multiple range test.
