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

Figure 3

Effects of water stress (WS) on the activities of total SOD (a) and SOD isoenzymes including Cu/Zn-SOD (b), Fe-SOD (c), and Mn-SOD (d) in Cerasus humilis leaves of Huai’rou (HR) and Nongda4 (ND4). Samples were collected after 21 d of treatment. The data shown 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.
