Figure 1

Leaf water content in ‘Hull Thornless’ subjected to drought stress and re-watering. Control: well-watered; D: drought stress treatments of 10, 15, and 20 days, and R: 5 days after re-watering. Data are means±S.D. (n = 3). Values designated over the bars in different letters are significantly different at p < 0.05. 

Figure 2

Electrolyte leakage in ‘Hull Thornless’ subjected to drought stress and re-watering. Control: well-watered; D: drought stress treatments of 10, 15, and 20 days, and R: 5 days after re-watering. Data are means±S.D. (n = 3). Values designated over the bars in different letters are significantly different at p < 0.05.

SOD (A) and POD (B) activities in ‘Hull Thornless’ subjected to drought stress and re-watering. Control: well-watered; D: drought stress treatments of 10, 15, and 20 days, and R: 5 days after re-watering. Data are means±S.D. (n = 3). Values designated over the bars in different letters are significantly different at p < 0.05
