摘要：

SYNOPSIS. Conjugation in Stentor coeruleus was investigated, using a standardized culture technic which yielded large numbers of mating pairs within a single culture. Spontaneous bursts of selfing occurred during a definite interval in the development of a culture. Structurally distinct preconjugator cells appeared immediately before as well as during the initial stages of a burst of conjugation. Mating pairs were formed by the union of 2 preconjugators. Mixing 8 stocks in all possible combinations of pairs and observing their subsequent response revealed they were separable into 2 complementary mating types. The majority of mating pairs formed in mixtures of stocks consisted of individuals of different mating types. It is suggested that control of mating types in the ciliate order Heterotrichida may be of a somewhat different nature from that found in other ciliates. Copyright © 1969, Wiley Blackwell.
