Table 1 - Effect of seed dehydration and melatonin treatment on water deficit of embryo tissues of group 1 (1) and group 2 (2) 18-hour-old pea seeds grown on water or Hoagland 1/2 medium
Variant/germination medium | Water deficit (%) | |
Water (group 1) | Hoagland's medium ( group 2) | |
Control | 8.68 ± 1.11a | 8.09 ± 1.32 a |
+ melatonin | 9.37 ± 1.28 a | 21.02 ± 1.22 b |
Dehydration | 20.25 ± 1.13 b | 16.82 ± 1.13 c |
Dehydration + melatonin | 21.59 ± 1.22 b | 22.21 ± 1.2 b |
the table shows the arithmetic mean values and their standard errors. Statistically significant differences between mean values were determined using Tukey test in ANOVA programme, results marked with different letters are statistically significant at P ≤ 0.05.Water deficit of embryo tissues germinated on water or Hogland's medium ½ (%)
