국문 초록

水稻種子의 放射線感受性에 미치는 酸素의 影響을 究明코저 水稻品種 萬頃에 X-線을 處理한 後 酸素가 飽和溶存된 水溶液속에 種子를 浸漬하여 發芽 및 幼苗長을 調査하였고 旣往硏究된 麥類를 補助材料로 使用하여 比較하였던 바 다음과 같은 結果를 얻었다. 大麥水原 18號(水分含量 5.4%)와 小麥 農林4號(水分含量 6.7%)에 있어서는 酸素處理에 依한 障害가 뚜렷하여 發芽 및 幼苗長에 많은 減少를 보였고 特히 水原 18號는 農林4號보다 障害가 더욱 컸다. 그러나 水稻萬頃(水公含量 10.7%)은 酸素에 依한 障害가 거의 없어 發芽에는 극히 僅少한 減少를 보이는 듯하나 差異를 認定할 수 없고 幼苗長에는 全혀 差異가 없었다.

영문 초록

Dormant seeds of rice variety Mankyung (10.7% water content) was used for biophysical studies concerned with the influence of post- irradiation oxygen treatment on the manifestation of seedling and germination injury. Barley and wheat seed were also used along with rice to confirm the oxygen effectiveness. The results were summarized as follows: The irradiated rice seeds with 10.7% water content showed little or no changes in their germination and growth when the seeds were treated with oxygen, while barley and wheat seeds with water content of 5.4% and 6.7% respectively were significantly affected by oxygen. in their germination and seedling height. Injury on barley seedling was more pronounced than that on wheat.
