The results of study of embryo development in B. rapa plants, as well as the rate and the character of nutrient substances accumulation in their cells under slow horizontal clinorotation and laboratory control are presented. Significant similarity of the peculiarities of embryo differentiation and character of nutrient substance accumulation in both variants was shown. The cases of different deviations during embryo differentiation, and rate and quantity of reserve nutrient substances in their cells are revealed under clinorotation compared to the laboratory control.
