干旱和铅胁迫对刺槐和紫穗槐抗氧化酶活性的影响
Effects of Drought and Lead Stresses on Antioxidant Enzyme Activities of Robinia pseudoacacia and Amorpha fruticosa
摘要
Abstract
The effects of heavy metal Pb and drought stresses on the antioxidant enzyme activities and ma-londialdehyde concentration of Robinia pseudoacacia and Amorpha fruticosa in one-year old seedlings were studied with pot experiments for the selection of tree species with strong resistance. The results showed that lead stress at higher concentration (1 000 - 3 000 mg ? Kg~') and at lower (300 ~ 500 mg ? Kg"1) could improve activity, could improve SOD and POD activities, respectively. Both water and lead stresses could improve antioxidant enzyme activities of the leaves. Based on a comprehensive analysis, the resistance of A. Fruticosa was better than R. Pseudoacacia. Antistress abilities to Pb were in the order of A. Fruticosa seedling>A. Fruticosa cutting>J?. Pseudoacacia seedling.关键词
