[Objective]The aim was to study the inhibitory effects of Eichnornia crassipes, Gracilaria lemaneiformis and N-phenyl 2-naphtyyl-amine on growth of C.marina.[Method]E.crassipes root dry power concentration was 0,0.1,0.5,1.O,1.5 g/L respectively,G.lemaneiformis fresh tissue concentration was 0,0.1,0.5,1.0,2.O g(FW)/L,and N-phenyl 2-naphthylamine concentration was 0,0.5,1.0,5.O,10.0 mg/L.[Result]The results showed that growth of C. Marina which was initial concentration was 1.6 ×106 cell/L was inhibited apparently when the concentration of E. Crassipes roots dry powder were 1.0 and 1.5 g/L,the concentration of N-phenyl 2-naphthylamine was 1.0,5.0,10.0 mg/L and the concentration of G.lemaneiformis fresh tissue was 2.0 g(FW)/L.[Conclusion]The study lays a basis for deeply researching the effects of E.crassipes and G.Lemaneiformis on growth of C.marina.%[目的]研究凤眼莲根(Eichnornia crassipes)、龙须菜(Gracilaria lemaneiformis)和N-苯基-2-蔡胺对海洋卡盾藻(Chattonella marina)生长的抑制效应.[方法]凤眼莲根粉末浓度分别设为0、01、0 5、1 0、1.5 g/L,龙须菜新鲜组织浓度分别设为0、0.1、0 5、1.0、2.0g(FW)/L,N-苯基-2-蔡胺浓度分别设为0、0.5、1.0、5 0、10.0 mg/L.[结果]1 0、1.5g/L凤眼莲根粉末,1 0、5.0和10.0 mg/L N-苯基-2-萘胺及2.0g(FW)/L龙须菜新鲜组织对起始密度为1.6×106个/L的海洋卡盾藻生长表现出明显的抑制作用.[结论]该研究可为进一步研究凤眼莲和龙须菜对海洋卡盾藻生长的影响奠定基础.
