AsA and GSH concentrations in stylo in the two Mn treatments. AsA concentrations in leaves (a) and roots (b). GSH concentrations in leaves (c) and roots (d). Stylo seedlings were grown under normal conditions for 30 d and then treated with 5 or 400 μM MnSO4 for 10 d. Each bar indicates the mean of four independent replicates with standard error. The same letter represents no significant difference at the P = 0.05 level
