| 摘 要： | 通过测定水华微囊藻（Microcystis flosaquae）叶绿素α和SOD活力，研究了不同浓度香蒲（Typha orientalis）和穗状狐尾藻（Myriophyllum spicatum）水浸提液对水华微囊藻的化感抑制作用。结果表明香蒲和穗状狐尾藻水浸提液低浓度处理（分别为5、10、20 g/L）对水华微囊藻的叶绿素α影响不明显或略有促进作用，高浓度处理（分别为30、40 g/L）则有明显的抑制作用；香蒲和穗状狐尾藻水浸提液处理对水华微囊藻的SOD活性有明显影响，且存在剂量效应，浓度越高影响越大；穗状狐尾藻水浸提液对水华微囊藻的化感抑制作用强于香蒲。

| Abstract: | The allelopathy of typha orientalis and myriophyllum spicatum extracts on microcystis flosaquae were studied in this paper by measuring chlorophyll α and SOD activity of M. flosaquae. The results show that T. orientalis and M. spicatum extracts have no or a little stimulative effect on chlorophyll αof M. flosaquae at low concentrations （5,10 and 20 g/L）,and have a significant inhibitory effect at high concentrations （30 and 40 g/L）;T. orientalis and M. spicatum extracts have a significant effect on SOD activity of M. flosaquae,and there exists dose effect;M. spicatum extract has a stronger inhibitory effect than T. orientalis. |
