| 摘 要： | 采用3种不同剂量的60Co-γ射线辐照5个草莓品种的匍匐茎植株，对辐照引起的致死、损伤和生长抑制效应以及新的匍匐茎发生情况进行了研究。结果表明，经30-80Gy剂量的60Co-γ射线辐照处理后，5个草莓品种的匍匐茎植株均有死亡，死亡率在22-88.7%，且各品种的死亡率均有随着剂量增加而提高的趋势，但不同品种的死亡率随剂量变化的具体表现不同；植株叶片均有畸型现象发生；植株叶片长度、叶片宽度、植株高度和植株冠径的变化因品种和辐照剂量而异；匍匐茎发生率和匍匐茎数量显著下降。不同草莓品种对60Co-γ射线的辐射敏感性不同，“章姬”最敏感，“宝交早生”、“春旭”、“圣星”次之，“硕丰”最不敏感。章姬的辐照半致死剂量应在30Gy和50Gy之间，宝交早生、春旭和圣星的辐照半致死剂量应在50Gy和80Gy之间，而硕丰的辐照半致死剂量应在80Gy以上。

| Abstract: | The runner plants of five strawberry varieties were irradiated by three different doses of 60Co-γ ray, and the irradiation effect of lethality, lesion, growth restraint on runner plants and the production of new runner plants were studied. The results indicated there was the dead runner plant in five strawberry varieties treated by 60Co-γ ray within 30-80Gy. The death rate was between 22% and 88.7%, which raised with increase in the dose of 60Co-γ ray, but there were different death rate from the different variety. There happened abnomal leaves in all treatment. The change of the length and width of leaf, the height and size of plant was different with irradiation dosage and strawberry variety. The occurance rate and the quantity of the new runner decreased significantly. The different varieties had different sensitivity to the irradiation of 60Co-γ ray, the most sensitive variety was “akihime”, the second was “hokowase”, “chunxu” and “shengxing”, “shuofeng” was most insensitive. The half lethal dose of irradiation to “akihime” was respond to between 30Gy and 50Gy, to “hokowase”, “chunxu” and “shengxing” was between 50Gy and 80Gy, to “shuofeng” above 80Gy. |
