Abstract
The studies of the cell cycle ofDiatoma hiemale var.mesodon have been continued on a population during the whole vegetative period (August–October 1976). The lapse of time between the maxima of the chromatophore division and the mitosis is 8 hours in the exponentional and stationary phase of growth of the population; during the decline and decay of the population it is shortening to 2–4 hours. The sequence of phases is maintained, but the stage of praemitotic stagnation is shortened to a minimum. During the stage of the chromatophore division a relationship was found between time lapse and chromatophore number per cell. The cell cycle (asexual life cycle) ofDiatoma hiemale var.mesodon has been schematically illustrated during optimal development and its different stages are discussed.
