Results are the means of 10 repetitions from three independent experiments. se of the means was less than 10%. For comparisons between the means, one-way analysis of variance was used. Values in each row followed by different letters are significantly different at P ≤ 0.01. C, Control; D, drought-stressed; R1, rehydrated for 1 d; R2, rehydrated for 4 d; BUT, butyl hydroperoxide.
