| 摘 要： | １９９３年３月２６日在大鹏湾进行赤潮调查时，对所采获的夜光藻进行室内培养实验。结果观察到夜光藻在无性繁殖时的一种不等分裂方式，而且在分裂过程中食物泡没有消失。认为这种分裂方式对于夜光藻种群在特定条件下的增长可能更有效和迅速。

| Abstract: | Samples of Noctiluca scintillans were taken from Dapeng Bay, Guangdong, inMarch 26, 1993. Under experimental conditions. the mother cell of Noctiluca scintillans divided into two unequal daughter cells, both of which in some cases containedfood vacuoles during its asexual reproductive process. It is considered that reproduction of a smaller cell by a bigger cell is a remarkably effective and rapid way toincrease individual nutnbers for the population. The findings could explain why thepopulation structure of Noctiluca scintillans is always composed of different-sizedcells and the very rapid formation of red tide of Noctiluca tcintillans under favorable conditions. |
