Effects of NaF priming on the superoxide anion (O2•−) (A, G), hydroxyl radical (•OH) (B, H), hydrogen peroxide (H2O2) (C, I), malondialdehyde (MDA) contents (D, J), lipoxygenases (LOX) activity (E, K), and nitric oxide (NO) content (F, L) in shoots and roots of barley plants under Al-stress. Values are means ± standard errors (SEs) (n = 5). According to Tukey's test, bars that are accompanied by the same alphabet are not significant among the treatments at P≤0.05
