受小剂量γ射线处理植物种子和柞蚕卵提高生命力的启示,1978年我们用137铯—γ射线照射量:5γ、10γ、10γ、20γ处理苹果花粉,并对幼果期、初果期、盛果期三种树龄果树进行授粉试验。经过多次重复和统计分析结果表明:5γ照射花粉是促进提高花粉发芽率和花序花朵座果率的最佳照射量,用5γ处理花粉,小区试验花粉发芽率平均提高62％,生产对比试验发芽率提高12～89％。用5γ照射花粉分别对幼果期、初果期、盛果期三种树龄果树授粉试验,花序花朵座果率分别提高4～10％,12～24％,生产对比试验花序花朵座果率分别提高4～16％,10～56％。
In 1978, we used 137 cesium-γ ray irradiation dose: 5γ, 10γ, 10γ, 20γ to deal with the apple pollen, and the young fruit, early fruit, Sheng Fruit age three fruit trees for pollination test. After many repetitions and statistical analysis, the results showed that: 5γ irradiation pollen is the best irradiation to improve the germination rate of pollen and inflorescence fruit rate, pollen was treated with 5γ, pollen germination rate increased by 62% Rate increased by 12 ~ 89%. Pollination experiments were conducted on fruit trees of young age, early fruit stage and full fruit stage respectively by using 5γ irradiation pollen, the fruit rate of inflorescence increased 4 ~ 10% and 12 ~ 24%, respectively, Increase 4 ~ 16%, 10 ~ 56%.
