FIGURE 3

Influence of different drought stress levels on the activities of (A) superoxide dismutase (SOD), (B) peroxidase (POD), (C) catalase (CAT), (D) Ascorbate peroxidase (APX), (E) Dehydroascorbater eductase (DHAR), and (F) monodehydroascorbater eductase (MDHAR) in three maize hybrids. Capped bars above means represent ±SE of three replicates. Small alphabetical letters above means denote the significant differences among treatment with in a maize hybrid at P ≤ 0.05. Ck, control (100% FC); LD, low drought (80% FC); MRD, moderate drought (60% FC); and SD, severe drought (40% FC); FC, Field capacity.
