摘要
采用微量移液稀释法对海洋原甲藻进行无菌培养，以研究温度、盐度、光照强度和pH对海洋原甲藻增长的效应。结果表明，海洋原甲藻最大增殖速率发生在温度为(25±1)℃、盐度为31、光照强度为3000lx、pH为8.0的环境条件下。海洋原甲藻在温度18—28℃、盐度为25—34、光照强度为1000—6500lx、pH为7.5—8.3范围内适宜生长。这一结果与观测到的海洋原甲藻赤潮发生时环境条件相近，其中温度的效应最为明显。
Prorocentrum micans Ehrenb which has cau sed heavy red tides in the costal sea area of China was placed in aseptic clonal culture by micropipette washing. Experiments showed that the growth of the red tide organism P. micans required suitable environment like temperature, sali nity, irradiance, pH. and other chemical factors. P. micans could grow from 18℃ to 28℃, 25 to 34 salinity, irradiance from 1000lx to 6500lx and 7.5 to 8.3 pH. The highest growth rate was observed at temperature (25±1)℃，salinity 31, irradiance 3000lx and pH8.0. The results and field observations indicated that the development of the Prorocentrum micans red tide is strongly dependent on the temperature.
