| 摘 要： | 本文研究了不同剂量的60Coγ射线和紫外线辐照对帚型山桃、凯特杏、黑宝石李3种果树花粉后其发芽率及远缘杂交坐果率的影响。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。3种果树花粉的辐射敏感性有明显差异,其中黑宝石李花粉最敏感,花粉发芽率降低最明显;帚型山桃次之;凯特杏的花粉最不敏感。辐照后的低花粉发芽率降低了远缘杂交的坐果率。

| Abstract: | Pollens of Zhouxingshantao peach trees,apricot cultivar Katy and plum cultivar Friar were irradiated by different doses of()~(60)Co γ-rays and ultraviolet to study the radiation effect on the pollen germination and distant hybridization settings.The germination percentages of the pollen irradiated by()~(60)Co γ-rays and ultraviolet were lower than those of the controls.The pollens of the tested fruits have different sensitivities to()~(60)Co γ-rays and ultraviolet: the Friar pollen was the most sensitive to the radiation,and the Katy was the least.With the germinate percentages of the irradiated pollen dropping,the distant hybridization fruit setting percentage also lowered. |
