Abstract: | Counts of nuclei in enzyme digested endosperms of barley cultivarBomi show that the final number of cells, 170000, is reachedbetween 18 and 21d after anthesis. Based on the number of cellprofiles in transverse mid-grain sections, starchy endospermcells divide up to day 14. Thereafter, cell proliferation isrestricted to the aleurone layer.
