The development of embryos in Brassica rapa L. in microgravity

In this work we present the results of the comparative cytoembryological research on embryos of an identified age that were produced in microgravity and in the ground laboratory control. A considerable similarity was found between the rate of embryo development and degree of their differentiation in both variants. Abnormalities in the process of embryo formation and acceleration in development of the endosperm were revealed at the early stages of embryogenesis in microgravity.
