Table 2.

Osmotic potential and H₂O₂ content (Mean ± SE) measured during drought (D1-D5) and at recovery (R) in the tolerant and the susceptible groups from well-watered (W) and drought (D) fields. Different letters indicate significant differences by one-way ANOVA (SNK method) during drought period (D1-D5). “*” indicates significant difference at p < 0.05 by independent t-test between the tolerant and the susceptible groups at the recovery stage
