Fig. 4.

The enzymes activity (A–E) and H2O2 (F), Proline (G) and MDA content (H) in the leaf of As-treated Artemisia annua plants. Bars represent SEs, based on 3 independent experiments. Artemisia plants were co-inoculated with P. indica and supplemented with different arsenic concentrations or remained un-inoculated and treated with the same arsenic concentrations. The data are the mean values of three biological replicates with ±standard error. The same lower-case letters within each column indicates no significant difference among treatments (p < 0.05).
