Abstract
In order to clarify the effect of fractional dosage on sterility in the treaited generation, dormant Seeds of a variety "Norin No. 29" of rice and of a variety "Sekitori Sai No. 1" of barley were treated with X-radiation. The irradiation was given in two fractions of 10.000 r. at one, two or four days interval and a single dose of 20.000 r. in both species. The fractional dosage produced more sterility than the single dose in the first generation of rice as well as of barley, as shown at Table I and 3, and the increment of rest period elapsing between first irradiation and the next gave more sterile spikes). This result obtained with dormant seeds probably is due to the Storage of seed after the cessation of X-raying, also to the X-ray-sensitivity produced by the first irradiation.
