东海具齿原甲藻的扫描电子显微结构

Scanning electron-microscopic study on Prorocentrum dentatum from the East China Sea

在光学显微镜分析鉴定的基础上 ,通过高分辨率的扫描电子显微镜 ,对东海赤潮原甲藻标本和美国国家海洋藻种中心 (CCMP)的具齿原甲藻 (Prorocentrumdentatum )藻株 (CCMP15 17)的细胞表面结构进行观察和比较 ,认为两者为同一种类 .在分析大量文献资料的基础上 ,可以认为发生在我国东海水域的赤潮原甲藻种类是具齿原甲藻 (Prorocentrumdentatum) ,而非新种 .

There is an argument whether the bloom causative species of the East China Sea is Prorocentrum dentatum or a new species. Based on the scanning electron-microscopic study, we compared the detailed surface structure of the sample from the East China Sea and Prorocentrum dentatum strain (CCMP1517) from the Provasoli-Guillard National Center for Culture of Marine Phytoplankton, USA. The results showed that these two samples belonged to one species. After reviewing literatures,it can concluded that the bloom causative species of the East China Sea is Prorocentrum dentatum, rather than a new species.
