| 摘 要： | 采用盆栽方法,对吊竹梅用pH值为6.7(对照)、5.6、4.5、3.5、2.5、1.5的模拟酸雨进行喷雾处理,测定其生物量、花青素相对浓度、叶绿素含量、硝酸还原酶活性(nitrate reductase, NR)、脯氨酸含量、超氧化物歧化酶(superoxide dismutase, SOD) 活性、过氧化物酶 (peroxidase, POD)活性、过氧化氢酶(catalase, CAT)活性、丙二醛(malondialdehyde, MDA)含量和质膜透性等指标。结果显示,吊竹梅单株干质量、叶绿素含量、NR活性、花青素相对浓度、CAT活性均呈下降趋势;SOD活性呈先上升后下降趋势;脯氨酸含量、POD活性、MDA含量和质膜透性均呈上升趋势。综合分析表明,模拟酸雨pH值为5.6~3.5处理,吊竹梅生长和抗氧化能力受影响较小,而观赏性不受影响;模拟酸雨pH值为2.5处理,其生长受抑制程度和抗氧化能力下降幅度增大,对其观赏性几乎无影响;模拟酸雨pH值为1.5处理,其生长和抗氧化能力严重受抑制,有明显伤害症状,观赏性急剧下降。

| Abstract: | Zebrina pendula plants 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 reductase 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. pendula was 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 became 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. |
