Lipid peroxidation and membrane injury in roots. Seedlings were grown on MS agar plates for 28 d and then in hydroponic medium for 28 d. A and B, Seedlings were treated with or without 500 μm AlCl₃ for 24 h and then stained with Schiff's reagent to visualize lipid peroxidation (A) or with Evans blue to detect cell death (B) as described in “Materials and Methods.” C, Electrolyte leakage. Data are means ± se (n = 3). Values followed by the same letter are not significantly different according to Tukey-Kramer test (P < 0.05).
