| 摘 要： | 在pH值为2.0,3.0,4.0,5.6的模拟酸雨处理下,研究了3个不同类型革坪草叶片征状、叶绿素含量及叶片抗氧化系统的变化.结果表明,在不同pH值酸雨影响下,草坪草叶绿素含量、超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的活性随着pH值的下降呈下降趋势;过氧化物酶(POD)活性、丙二醛(MDA)相对含量和质膜透性(PMP)随着pH值的下降呈上升趋势.叶片仅在pH值2.0时才出现明显伤害征状.

| Abstract: | The changes in the lesion of leaf,chrlorophll content and antioxidant systems in three different tested turfgrass cultivars under pH2.0,pH3.0,pH4.0, pH5.6 simulated acid-rain, were investigated. The results showed that the chrolophyllous content,antioxidant enzymes,superoxide dismutase (SOD) and catalase (CAT) activities tended to decline with the decrease of pH. The reverse was true in the case of membrane permeability(PMP), relative malondialhyde(MDA) content and peroxidase (POD) activities.The visualized lesion was only found under the treament of pH2.0 simulated acid-rain. |
