| 中文摘要: |
| 为了解低剂量60Co-γ射线辐照花粉对贵长猕猴桃果实的影响，以市售猕猴桃商品花粉为材料，采用不同低剂量60Co-γ射线对花粉进行辐照处理，研究辐照花粉对猕猴桃果实生长发育、果实品质及耐贮性的影响。试验结果表明，与对照组（CK）相比：处理组果实乙烯生成速率、呼吸速率增加（CK＜G6＜G9），果皮硬度减小（CK＞G6＞G9）；G9辐照处理使果实畸果率升高，座果率、单果重、单果种子数下降，果实干物质、可溶性固形物、可滴定酸及Vc含量显著减少；G6辐照处理后果实生长发育及果实品质均与对照组无显著差异。本研究为低剂量60Co-γ射线辐照去除丁香假单胞菌猕猴桃花粉的应用提供了理论依据。 |

| In order to exploration how low-dose 60Co-γ ray irradiated pollen affect kiwifruit, commercial kiwifruit pollen was irradiated with different low-doses 60Co-γ rays and then the effects of irradiation pollen on fruit growth, fruit quality and storage property were studied. Experiment results showed that compared with control group (CK): irradiation treatment increased ethylene production and respiration rate (CK G6>G9), and G9 irradiation treatment increased fruit malformation rate, decreased fruit setting rate, fruit weight, fruit seed number, dry matter, soluble solids, titratable acid and Vc content, but there was no significant difference between G6 and control group in terms of fruit growth and fruit quality. This study provided a theoretical basis for application of kiwifruit pollen which was irradiatied by low-dose 60Co-γ ray to kill Pseudomonas syringae pv. actinidiae. |
