| 中文摘要 | the effects of la3+ on the antioxidant enzyme activities and the relative indices of cellular damage in cucumber seedling leaves were studied. when cucumber seedlings were treated with low concentrations of lacl3 (0.002 and 0.02 mm), peroxidase (po) activity increased, and catalase (cat) activity was similar to that of control leaves at 0.002 mm la3+ and increased at 0.02 mm la3+, whereas superoxide dismutase (sod) activity did not change significantly. the increase in the contents of chlorophyll (including chlorophylls a and b), carotenoids in parallel with the decrease in the level of malondialdehyde (mda) suggested that low concentration of la3+ promoted plant growth. however, except the increase in sod activity at 2 mm la3+, cat and po activities and the contents of pigments decreased at high concentrations of la3+ (0.2 and 2 mm), leading to the increase of mda content and the inhibition of plant growth. it is suggested that lanthanum ion is involved in the regulation of active oxygen-scavenging enzyme activities during plant growth. |
