Embryological studies were undertaken to compare the normal development of cucumber endosperm and embryo with that observed after pollination with gamma-irradiated pollen (0.1 and 0.3 kGy). Delayed penetration of the pollen tube occurred at both irradiation doses. Endosperm and embryo development was also delayed, but was initiated within 6 days after pollination in 100% of embryo sacs at 0.1 kGy and in 70-80% at 0.3 kGy. Various abnormalities in endosperm and embryo cell structure confirmed progressive degeneration, which occurred earlier with the higher dose of irradiation. Degeneration increased dramatically; only 30-40% of the embryos reached the globular stage 15 days after pollination.
