title: Effect of culture density on sexual reproduction of Ardissonea crystallina (Bacillariophyta) inhabiting the Black Sea
abstract: One of the key factors that affect the sexual reproduction of diatoms is the cell concentration in the mating experiments. The concentration of pheromones, which probably initiate gametogenesis in the mixture of cells of opposite sexes, depends on the culture density. The influence of the cell concentration and inoculation pattern on the sexual reproduction has been studied in the experiments with the taxonomically important marine diatom Ardissonea crystallina (C. Agardh) Grunow. Several clones
