模拟酸雨对吊竹梅生长及抗氧化能力的影响
Effects of simulated acid rain on the growth and antioxidant activity of Zebrinapendula
摘要
Abstract
Zebrinapendulaplants were sprayed with simulated acid rain at different pH values (6.7,5.6,4.5, 3.5,2.5,1.5)in pot experiments,and the biomass,relative anthocyanin concentration,chlorophyll content, nitrate reductase activity,proline content,antioxidase activity (including superoxide dismutase,peroxidase and catalase),malondialdehyde content,and membrane permeability were determined.With decreased pH value from simulated acid rain,the dry weight,relative anthocyanin concentration,chlorophyll content,nitrate re-ductase activity and CAT activity decreased.SOD activity showed a trend of initial increase and then decrease. Proline content,POD activity,MDA content and membrane permeability increased with decreasing pH value. An integrated analysis indicated that under simulated acid rain-induced pH values 5 .6-3 .5 ,the growth and antioxidant activity of Z.pendulawas only slightly inhibited and there was no effect on ornamental quality;under a simulated acid rain-induced pH value 2 .5 ,the inhibition effect on growth and antioxidant activity be-came heavier and there was a slight effect on ornamental quality;under simulated acid rain-induced stress of pH value 1.5,the inhibition effect was large and there were visible injury symptoms on leaves,with a sharp decline in ornamental quality.关键词
