Using the method of ,3,H-TdR incorporation, this paper studied the change of DNA synthesis during the early period of germination of wheat seeds irradiated by low energy N,+, heavy ion. The results showed: 1) the low energy N,+, heavy ion was also able to induced a unscheduled DNA synthesis (UDS) in seed embryos of wheat: 2) the peak of the UDS occurred at the 6 h after seeds soaking, being 4h earlier than the peak of the normal DNA synthesis of seed embryos: 3) the rate of UDS was roughly in positive proporation to irradiation doses: 4) the level of the normal DNA synthesis decreased with the increase of the UDS in the wheat seed embryos irradiated.
