Effects of low pH on [ascorbate (ASC) + dehydroascorbate (DHA)] (a, i), ASC (b, j) and DHA (c, k) concentrations, ASC/(ASC + DHA) ratio (d, l), [reduced glutathione (GSH) + oxidized glutathione (GSSG)] (e, m), GSH (f, n) and GSSG (g, o) concentrations, and GSH/(GSH + GSSG) ratio (h, p) in Citrus grandis and Citrus sinensis leaves (a-h) and roots (i-p). Bar represent mean ± SE (n = 8). Different letters above the bars indicate a significant difference at P < 0.05
