铜和模拟酸雨复合胁迫对酸模铜富集、生长及抗氧化酶系统的影响
Combined effects of copper and simulated acid rain on copper accumulation,growth,and antioxidant enzyme activities of Rumex acetosa.
摘要
Abstract
A pot experiment was conducted to study the combined effects of Cu (0-1500 mg·kg-1 ) and simulated acid rain ( pH 2. 5-5. 6) on the copper accumulation, growth . and antioxidant enzyme activities of Rumex acetosa. With the increasing concentration of soil Cu. the Cu accumulation in R. acetosa increased, being higher in root than in stem and leaf. The exposure to low pH acid rain promoted the Cu uptake by R. acetosa. With the increase of soil Cu concentration and/orof acid rain acidity, the biomass of R. acetosa decreased. leaf and root MDA contents increased and had good correlation with soil Cu concentration. and the SOD and POD activities in leaf and root displayed a decreasing trend after an initial increase. This study showed that R. acetosa had a strong adaptive ability to Cu and acid rain stress. exhibiting a high application potential in the remediation of Cu-contaminated soil in acid rain areas.关键词
