To investigate the stimulating effects of the low- dose radiation, the seeds of chinese cabbages (Brassica campestris L. cv. Hanyoreum and cv. Tropic emperor) were irradiated at the dose of 0.5 Gy~20 Gy with the ${gamma}$-ray radition. In case of ¡®Hanyoreum¡¯cultivar, there were no significant promoting effects on the germination rate except the 0.5 Gy irradiated group. The increase in seedling height and fresh weight in 8 Gy and 12 Gy irradiated groups was 20% and 40%, respectively, which suggested the stimulating effect of the low-dose radiation on the early growth. In case of¡®Tropic emperor¡¯cultivar, the germination rate of 1 Gy irradiated group increased approximately 10% and the seedling height and fresh weight of 1 Gy and 12 Gy irradiated group in the greenhouse 20% on the average, and plant height and fresh weight of 0.5 Gy and 4 Gy irradiated group in the field increased 10% and 20% on the average, respectively.
