By 3 days after pollination the central cell was filled with endosperm cells. At first all cells of endosperm underwent division, later cell division was limited mainly in the peripheral region. 10 days after pollination the epidermal layer ceased its periclinal division and became the aleurone layer. Cell division persisted in the subepidermal 'cambium-like layers until the caryopsis nearly matured. Ceils of the inner region of endosperm became enlarged. Several layers of transfer cells were formed at the basal part of the endosperm. Starch grains appeared in endosperm cells on the 9th day after pollination. 10 days after pollination, lipid bodies occurred in the aleurone layer and the underlying layers. 13 and 15 days after pollination, the small vacuoles of aleurone cells contained protein and 20 days after pollenation they became aleurone grains. By 15 days after pollination pro tein bodies were formed in starch endosperm. Storage reserve deposition continued until the grain ripened. A correlation between endosperm and emoryo development was also observed.
