摘要
分析了东海原甲藻 (ProrocentrumdonghaienseLu)显微结构 ,并与具齿原甲藻 (Prorocentrumden tatumStein)模式种和Schiller的钝头原甲藻的描述等进行了比较 ,结果表明 ,它们之间的形态结构和个体大小具有很大的差别 ,这些差异远超出了同种个体因环境不同所造成的形态变化范围 .从细胞形态及其表面结构可以判断 ,日本、韩国海区所记录并报道的“P .dentatum”与我国东海的东海原甲藻应属同一种 .因此可以认为 ,我国东海赤潮高发区以及在韩国、日本海区的出现的高生物量 (highbiomassbloom formingspecies)赤潮原甲藻不是Stein所发表的具齿原甲藻 ,而是东海原甲藻 ,并对其进行了进一步修订 ,其种名应为东海原甲藻ProrocentrumdonghaienseLu .
In this paper,the detailed morphology of Prorocentrum donghaiense was studied.Taxonomic comparison was made between P.donghaiense and other relevant Prorocentrum species. The results suggested that distinct differences existed among them with respect to their conservative characteristics of morphology and cell sizes. This kind of discrepancy was far beyond that of individual variations within same species due to environmental factors. Therefore, the high biomass bloom-forming species in the East China Sea was not real Prorocentrum 'dentatum' Stein, but P. donghaiense Lu that was re-described in the present paper.P. donghaiense appeared in the East China Sea,and P.'dentatum' occurred in Japanese and Korean waters should be the same species.
