Abstract
Ultrastructural examination of 7-day-old rye proembryos did not reveal distinct differences in the cell structure of its particular parts. It was noted, however, that in the cells of the apical part vacuoles and multivesicular bodies were more numerous than, in the basal part. These specific features of the cells of the apical part of the proembryo (together with data of other authors) seem to indicate an early stage of development of the embryonal scutellum.
