Fig 10. Effects of P deficiency on the contents of ASC, ASC+DHA, GSH, and GSH+GSSG, and on the values of ASC/(ASC+DHA) and GSH/(GSH+GSSG) in leaves (A-F) and roots (G-L) of C. grandis.

Each bar represents mean ± SD (n = 4). Differences among the treatments were analyzed by Student’s t-test. Different letters above the bars indicate a significant difference at P < 0.05.
