[Role of gravitational force in the early embryogenesis of the teleost Brachidanio rerio].
The effect of turning and clinostating, exposures on the early embryogenesis of the teleost B. rerio was investigated. The eggs turned immediately after fertilization with their animal pole downwards and kept so till the formation of the axial complex developed in an absolutely normal way. Most eggs also developed normally during clinostating, when kept in the inclined and horizontal clinostats. During this exposure eggs of some clutches perished. They were those eggs which were unable to develop near the lower limits of the temperature range characteristic of B. rerio development (18-19.5 degrees C).
