Relative water content (RWC) in leaf disks of 24-day-old pea plants grown from the control (C), hydroprimed (H), and hydroprimed with an aqueous solution of 50 μM melatonin (H-MEL50) or 200 μM melatonin (H-MEL200) seeds.

|---|---|---|---|---|
| Variant | C | H | H-MEL50 | H-MEL200 |
| Time | ||||
| T0 | 90.4 ± 0.36a | 90.8 ± 1.36a | 92.3 ± 1.75a | 91.9 ± 0.88a |
| 24 h | 102.9 ± 4.02c | 104.0 ± 1.74c | 108.6 ± 3.73d | 110.0 ± 3.89d |
| 48 h | 98.5 ± 2.68b | 105.8 ± 2.30cd | 102.5 ± 0.75c | 104.8 ± 2.88c |
Measurements were performed at T0 (before PQ treatment) and after 24 and 48 h of disk incubation in 75 μM PQ solution. The results are expressed as mean values of about 5 measurements ± SEM. Two-way ANOVA and Duncan’s post hoc test were performed. The small letters next to the values show statistical significance. RWC ANOVA results: Variant (C, H, H-MEL50, and H-MEL200) F(3;32) = 9.11 p < 0.0002; Time (T0, 2, 4, and 6 h) F(2;32) = 166 p < 0.0001; and interaction Variant × Time F(6;32) = 3 p < 0.02.
