We present the effect of X-ray irradiation of buckwheat seeds on the growth of seedlings. The highest growth was observed when irradiation dose was 200 mGy, after two weeks, where the dose was changed from 20 to 1000 mGy. When the number of the seeds for the experiment was increased from 10 to 50 200 mGy irradiation also showed the growth promotion of the seedlings (T-test showed p = 0.02) .
