Figure 5

SOD, CAT, POD and APX activity under different intercropping treatments (maize monocrop (MMC), wheat monocrop (WMC), intercropping maize (IM), and wheat (IW) crops) and nitrogen treatments in 2019 and 2020. Different lower-case letters show a significant difference among intercropping treatments under both N rates. “*” above bars indicates a significant difference between the monocropping and intercropping treatments at *P < 0.05; **P < 0.01. Note: CAT, SOD, POD and APX indicate catalase, superoxide dismutase, peroxidase and ascorbate peroxidase activity, respectively.
