| 摘 要： | 小白菜根细胞质膜上存在氧化还原系统。1 mg/L Cd使2个小白菜品种的根细胞质膜NADH氧化速率显著升高,对Fe(CN)63-和EDTA-Fe3 还原速率无明显影响;10 mg/L Cd使2个小白菜品种根细胞质膜的NADH氧化速率、Fe(CN)63-和EDTA-Fe3 还原速率显著降低,说明高浓度Cd抑制了小白菜根细胞质膜的氧化还原系统活性。Cd处理后,2品种小白菜根细胞质膜NADPH氧化速率表现不同趋势。

| Abstract: | The redox system existed in root plasma membrane of pakchoi.1 mg/L Cd significantly increased the oxidation rate of NADH, and had no effects on the reduction rates of Fe(CN) 63-and EDTA-Fe3 of plasma membrane in roots of two pakchoi cultivars.10 mg/L decreased the oxidation rate of NADH,the reduction rates of Fe(CN)63-and EDTA-Fe3 of plasma membrane in roots of two pakchoi cultivars.The oxidation rate of NADPH had different tendency between two cultivars in presence of Cd. |
