通过室内实验研究了塔玛亚历山大藻对东海原甲藻、海洋卡盾藻和赤潮异弯藻的化感作用。我们研究了A. tamarense，C. marina、东海原甲藻（P.donghaiense）和东海原甲藻（H.在共培养条件下，研究了赤霞珠对A. tamarense文化在各个生长阶段，对三个有害藻华（HAB）形成藻类。在与A. tamarense，C. marina和H.在高密度下，赤潮藻的生长受到显著抑制，而东海原甲藻的生长则因接种比例的不同而不同。tamarense和P.donghaiense。当东海原甲藻：A. tamarense），东海原甲藻的生长受到明显抑制，而东海原甲藻的生长在9：1的比例下与对照基本相同。东海原甲藻、C. marina和H. akashiwo与A. tamarense的研究表明，化感作用可能是藻类竞争和浮游植物演替的重要因素之一。塔玛伦斯此外，A. tamarense培养对这3种赤潮藻均有抑制作用，且这种抑制作用随藻的不同生长阶段而不同。tamarense与亚历山大藻细胞中PSP毒素含量的报道值平行。这表明PSP毒素可能参与了A. tamarense。然而，PSP毒素在pH 7以上的快速分解和失活削弱了这种可能性。进一步研究了与紫云英化感作用有关的化感物质。今后需要开展塔马拉人活动。
We investigated the allelopathic properties of Alexandrium tamarense (Laboar) Balech on the growth of Prorocentrum donghaiense Lu, Chattonella marina (Subrahmanyan) Hara et Chihara and Heterosigma akashiwo (Hada) Hada in a laboratory experiment. We examined the growth of A. tamarense, C. marina, P. donghaiense and H. Akashiwo in co-cultures and the effect of filtrates from A. tamarense cultures in various growth phases, on the three harmful algal bloom (HAB)-forming algae. In co-cultures with A. tamarense, both C. marina and H. akashiwo were dramatically suppressed at high cell densities; in contrast, the growth of P. donghaiense varied in different inoculative ratios of A. tamarense and P. donghaiense. When the ratio was 1:1 (P. donghaiense: A. tamarense), growth of P. donghaiense was inhibited considerably, while the growth of P. donghaiense was almost the same as that of the control when the ratio was 9:1. The growth difference of P. donghaiense, C. marina and H. akashiwo when co-cultured with A. tamarense indicated that the allelopathic effect may be one of the important factors in algal competition and phytoplankton succession involving A. tamarense. In addition, the filtrate from A. tamarense culture had negative impacts on these three HAB algae, and such inhibition varied with different growth phases of A. tamarense in parallel with reported values of PSP toxin content in Alexandrium cells. This implied that PSP toxin was possibly involved in allelopathy of A. tamarense. However, the rapid decomposition and inactivation of PSP toxin above pH 7 weakened this possibility. Further studies on the allelochemicals responsible for the allelopathy of A. tamarense need to be carried out in future.
