摘要

慢原甲藻是一种有毒甲藻,有报道称其能够形成赤潮, 但国内外对其生长方面的研究几为空白。本文研究了温度、盐度、光照、起始密度、大量元素浓度、微量元素浓度以及维生素浓度等7种环境因子对慢原甲藻(Prorocentrum rhathymum)生长的影响。结果显示, 慢原甲藻的适宜生长条件为温度20—30℃, 盐度30‰—40‰, 光照67.5—121.5μmol·m-2·s-1, 大量元素、微量元素和维生素浓度分别为f培养基对应组分的1/2—2倍、1/8—1/2倍、1/2—4倍。起始密度小于8000个·mL-1时, 最大细胞密度与起始密度正相关。

Abstract

Prorocentrum rhathymumis a harmful dinoflagellate species of red tide algae. However, there were nearly no researches on the growth of Prorocentrum rhathymumin China. In this paper, the effect of temperature, salinity, illumination, initial cell density and nutrients on the growth of Prorocentrum rhathymumwas studied. The results showed that the optimum
