Figure 1

Effect of pretreating with different concentrations of melatonin (MT) on growth of leaves of naked oat seedlings under salt stress. (A) Plant height; (B) stem thickness; (C) plant fresh weight; (D) plant dry weight. Values are mean ± standard deviation (n = 3). 0, 50, and 100 represent MT concentration (μM) in Figure 1. Asterisks; * and ** indicate significant difference (p < 0.05 and p < 0.01, respectively) compared with mock coating (0 μM). Measurement was carried out after six days of the salt plus MT pretreatmemt.
