Drought Tolerance Is Correlated with the Activity of Antioxidant Enzymes in Cerasus humilis Seedlings

Figure 4

Effects of water stress (WS) on the activities of catalase (CAT) (a) and ascorbate-glutathione (AsA-GSH) cycle enzymes including ascorbate peroxidase (APX) (b), dehydroascorbate reductase (DHAR) (c), monodehydroascorbate reductase (MDAR) (d), and glutathione reductase (GR) (e) in Cerasus humilis leaves of Huai’rou (HR) and Nongda4 (ND4). Samples were collected after 21 d of treatment. The data are the mean of at least three replicates with standard errors shown by vertical bars. Asterisk () indicates significant difference with control groups (well-watered) at the 0.05 level of probability by Duncan’s Multiple-Range Test.
