Figure 5.
The change in APX, POD, CAT, and SOD activities among CA157, CA52, and CL122. (a) Variation tendency of APX; (b) variation tendency of POD; (c) variation tendency of CAT; (d) variation tendency of SOD; X-axis represented the value of activity; Y-axis represented the time after low-temperature stress. Data are presented as mean ± SE; *p < 0.05.
