Figure 5. Effect of Mn and Zn induced oxidative stress on CAT activity of P. nicotianae at the stage of sporangiogenesis.

Figure 5

(A) Effect of different Mn concentrations treatment on CAT activity at the stage of sporangiogenesis. (B) Effect of different Zn concentrations treatment on CAT activity at the stage of sporangiogenesis. Different letters above columns are significantly different (P < 0.05) between experimental groups. Error bars are the standard error of the means (n = 3).
