Effects of NaF priming on glutathione S-transferases (GST) (A, G), phenylalanine ammonia-lyase (PAL) (B, H), polyphenol oxidase (PPO) (C, I), nitrate reductase (NR) (D, J), phytochelatins (PC) (E, K), and metallothioneins (MC) contents (F, L) in shoots and roots of barley plants grown 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
