[Development of Brassica rapa L. embryos under conditions of microgravity].
Results of comparative studies of the embryos of identical age formed under microgravity and ground laboratory control are presented. Significant similarity of a rate of embryo development and degree of their differentiation in both variants has been shown. The single cases of the disturbances in embryo formation, and also a certain acceleration of endosperm development at the early stages of seed formation in microgravity are revealed.
