摘要
通过连续观察和摄影，详细研究了夜光藻的二分裂和核分裂过程。发现夜光藻核分裂时具核外突细胞膜现象，双鞭毛配子和多种状态的配子结合。结果表明，二分裂是夜光藻的主要繁殖方式，核分裂形成营养细胞的机会甚微，且具有某种程度的性分化不完善。
This paper reports studies on the reproduction characteristics of Noctiluca scintillans through continuous observation (under light microscope) of the two kinds ofcell fission: binary fission and nucleus fission. The relationship between the two kinds of reproduction and the red tide of N. scintillans are discussed. Asexual reproduction by binary fission was found to be the main kind of reproduction in N. scintillans. The gametes released by nucleus fission could conjugate with each other,but the ratio was small (0.1% -0.2%) and conjugation did not aiways occur. Thezygotes could grow to 24.5-32.3μm but finally died without becoming typical vegetative cells. Gametes with 2 flagellates and zygotes with 3 or 4 flagellates were found. Other authors have not reported such finds. The taxonomy and incomplete sexualdifferentiation of N. scintillans are discussed.
