Comparison of reactive oxygen species scavenger activity under heat stress. The (A): Superoxide dismutase (SOD), (B): Catalase (CAT), and (C): Peroxidase (POD) activities in cucumber plant leaves. Experiments were performed using three randomly collected leaves from eight plants on day 14, at which point severely wilted plants were observed in the control group. All experiments were performed in triplicate, and the averages are graphed. Error bars represent the mean ± SD. Asterisks indicate statistical significance (Student’s t-test, ** p ≤ 0.05).
