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 (%)
