The reduced (AsA) and the oxidized (DHA) form of ascorbate as well as the reduced (GSH) and the oxidized (GSSG) form of glutathione were expressed as μmol g^–1 FW. Well-watered (WW), moderate drought (MD), and severe drought (SD). Means and SE of four replicates are shown. Different letters within the same stage indicate significant differences (P < 0.05) according to Duncan’s test.
