以 4 0 ,6 0 ,8 0 ,10 0kR 4种剂量的6 0 Coγ射线对豫芝 4号、郑 95- 8、豫芝 11号 3个芝麻品种的风干种子进行辐射处理后播种。结果表明 :种子处理后芝麻产量提高 4 93%～ 2 2 30 % ;不同品种或同一品种对辐射处理的剂量反应不同 ;各品种在其最佳剂量下 ,芝麻的农艺性状有所改进。
The dried seeds of three sesame varieties of Yuzhi 4, Zheng 95-8 and Yuzhi 11 were radiated with 60Co γ ray of 4 0, 60, 80 and 100 kR doses. The results showed that the yield of sesame seeds increased by 4 93% -2 22% after seed treatment. The dose response of different cultivars or the same cultivars to radiation treatment was different. The agronomic characters of sesame seeds were improved under the best dosage of each variety.
