Thymol attenuated ammonium-induced oxidative injury in rice seedlings. (A-B) Changes in TBARS content in root and shoot after NH4Cl exposure for 72 h. (C-F) Detection lipid peroxidation in leaf (C), loss of membrane integrity in leaf (D), and cell death in root (E), and cell death in leaf (F) after NH4Cl (20 mM) exposure with or without thymol (20 μM) for 72 h. The black arrow in (H) indicates the direction of root tip. Different lowercase letters in A-H indicate that the mean values of ten replicates are significantly different among different treatments (P < 0.05, ANOVA, LSD)
