The influence of oxygen on the induction by gamma radiation of mitotic delay in root tip cells of Vicia faba has been investigated for doses up to about 200 rads. There is no qualitative difference between the radiation effects in anaerobic and aerobic conditions. The oxygen factor, i.e., the ratio of doses required to produce equal mitotic delay under the two conditions is about 1.9 to 2.0. Mitotic delay is greater the earlier a cell is in interphase at the time of irradiation. Cells already in mitosis are not delayed during that mitosis, but suffer a delay in reaching the next mitosis. Various features of the mitotic delay suggest that some unidentified process of cellular development has been disturbed or retarded by irradiation.
