| 摘 要： | 随着银杏叶片的自然衰老，叶绿素含量、过氧化氢酶（CAT）活性明显下降，质膜渗漏、过氧化物酶（POD）活性不断增大，用1mmol/L硫代硫酸银（STS）处理，可减缓叶绿素含量和过氧化氢酶活性的下降，抑制过氧化物酶活性和质膜渗漏的增加，用10mmol/L的CaCl1溶液处理则具有相反的效应。

| Abstract: | With the natural senescence of ginkgo leaves, the content of chlorophyll and CAT activity decreases conspicuously while the membrane permeability and POD activity increase gradually. The treatment with 1 mmol/L STS could not only retard the decline of chlorophyll content and CAT activity but also check the increment of POD activity and membrane permeability. However, the treatment with CaCl 2 solution with the concentration of 10 mmol/L showed the opposite effect. |
