Abstract:

采用川蔓藻植株体与普通小球藻在再生水中共培养和使用再生水种植川蔓藻的种植水纯培养普通小球藻的方法,在实验室条件下研究了在滨海再生水河道中生长的沉水植物川蔓藻对小球藻的化感作用。结果表明,川蔓藻对普通小球藻具有显著的抑制作用。在共培养实验中,96h的抑制率为88.86%;在种植水纯培养实验中,96h的抑制率为48.91%。川蔓藻的种植水对普通小球藻的化感作用系数平均为-0.2448。川蔓藻的叶和根的种植水对普通小球藻均有抑制效果,96h的抑制率为叶34.71%,根14.12%;平均的化感作用系数叶为-0.1317,根为-0.0901;川蔓藻的根和叶均能释放化感物质,但抑制小球藻的化感物质主要通过叶释放。
