| 摘 要： | 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,96 h的抑制率为88.86%;在种植水纯培养实验中,96 h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,96 h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. |

| Abstract: | It is reported in this paper that the results of allolepathy test of Ruppia maritima L.on Chlorella vulgaris with co-culture in reclaimed wastewater and pure culture in the filtrate of liquious cultured the macrophyte.Chlo- rella vulgaris co-cultivated with Ruppia maritima in reclaimed wastewater indicated that Ruppia maritima had re- markable inhibition on Chlorella vulgaris.On co-culture experiment,at 96 h inhibition ratio was 88.86%;the competition of the nutrients had contribution to the growth which inhibited the ChloreUa vulgaris.On pure culture experiment with the filtrate of liquious cultured entire plant,leaves and roots of Ruppia maritima,the results of pure culture was inhibition activities on the growth of Chlorella vulgaris with the filtrate of entire plant,leaves and roots of Ruppia maritima,at 96 h inhibition ratio of leaves and roots were 48.91%,34.71% and 14.12%,the all olepathic effect of equal coefficient (E_t) of plant,leaves and roots were-0.2448,-0.1317 and -0.0901. The allolepathy parameter Et of Ruppia maritime on Chlorella vulgaris was derived from the modified Logistic equa- tion.Leaves and roots of Ruppia maritima were capable of releasing allelopathically active compounds,but the in- hibitory activity of allelopathically active compounds mainly came from the leaves tissue. |
