| 摘 要： | 观察不同剂量的60Coγ射线和紫外线为辐射源对帚型山桃、凯特杏、黑宝石李等三种果树花粉进行照射的发芽率.结果表明,经60Coγ射线和紫外线照射后3种果树花粉的发芽率与对照相比都明显降低,且均达到极显著水平;60Coγ射线比紫外线对花粉的发芽率影响明显;辐射后花粉发芽率降低多少依次为:黑宝石李>帚型山桃>凯特杏,辐射对黑宝石李的花粉的损伤最大、凯特杏花粉的损伤最小.

| Abstract: | Observed the pollens germination percentage of Zhouxingshantao,Katy and Friar were radiated by different doses of 60Co γ rays and ultraviolet.The results showed that the germination percentages of the pollen radiated by 60Co γ rays and ultraviolet are lower than the ones which have not been radiated,and reach the extremely remarkable.60Co γ rays affected more obviously than ultraviolet radiation.The pollens have different sensitivities to 60Co γ rays and ultraviolet: the friar pollen germination ratio dropped the most,and the Zhouxingshantao's,and the katy pollen;so is the injury degree to Friar pollen highest and Katy lowest. |
