摘 要 ：用0.1％-0.6％的硫丹喷施黄瓜幼苗4d后，叶绿素总量、叶绿素a、叶绿素b、原叶绿素、类胡萝卜素含量分别下降21.00％-38．57％、21.27％-38.69％、20.22％-38.24％、6．60％-49.24％和13.54％-68.85％；叶绿素酶活性上升16.51％-72．80％；δ-氨基乙酰丙酸（ALA）合酶和脱水酶活性分别下降14.14％-44.61％和4．38％-40．11％。讨论了硫丹影响叶绿素含量的可能机理。

Abstract:The leaves of cucumber (Cucumis sativus) seedlings were sprayed with 0.1 % - 0.6% thiodan, and after 4 days the contents of total chlorophyll, chlorophyll a, chlorophyll b,protochlorophyll and carotenoids were decreased by 21 .00% - 38.57%, 21 .27% - 38.69%, 20.22% - 38.24%, 6.60% - 49.24% and 13.54% - 68.85%, respectively. Thiodan at 0.1% -0.6% concentrations caused the promotion of chlorophyllase activity by 16.51 % - 72.80%, and decreased the activities of δ-aminolevulinate synthase and δ -aminolevulinat...
