C. chlamydogama Bold，C. reinhardti Dangeard，C. eugametos Moewus和C. MoewusiiGerloff在有丝分裂时显示出8条单倍体染色体，这一计数大大低于其他研究者先前报道的最后3种生物的每一种。在800英尺烛光的连续光照下，C. eugametos和C. Moewusii经历不同程度的多倍性，随后体细胞减少到单倍体数目独立于光发生。在所研究的其他2个物种中未观察到这种现象。有丝分裂和减数分裂基本上与大多数高等植物中观察到的相似。细胞分裂过程中的行为的其他细节的报告。两个特殊的修改的乙酰胭脂红染色技术进行了详细描述，因为它们被开发用于本研究。|| 摘要：N. D.水牛
C. chlamydogama Bold, C. reinhardti Dangeard, C. eugametos Moewus and C. moewusii Gerloff exhibit 8 haploid chromosomes at mitotic divisions, a count which is considerably lower than that previously reported by other investigators for each of the last 3 organisms named. When grown at 800 foot-candles of continuous illumination, C. eugametos and C. moewusii undergo polyploidy to varying degrees, with subsequent somatic reduction to the haploid number occurring independently of light. The phenomenon is not observed in the other 2 species studied. Mitosis and meiosis are essentially similar to that observed in most higher plants. Other details of cell behavior during division are reported. Two special modifications of the aceto-carmine staining technique are described in detail as they were developed for use in this study. || ABSTRACT AUTHORS: N. D. Buffaloe
