| 摘 要： | 用0—40krad~137Cs γ射线照射47个不同类型栽培大麦。结果表明,裸麦的辐射敏感性极显著大于皮麦。不同类型栽培大麦辐射敏感性的次序是:四棱裸大麦>六棱裸大麦>二棱裸大麦>四棱皮大麦>六棱皮大麦>二棱皮大麦。供试品种的敏感性可分为5个类型,即极迟钝型,迟钝型、中间型、敏感型和极敏感型。试验还表明,不同基因型大麦的细胞核体积与辐射敏感性无明显的相关关系,核体积的剂量效应曲线在30krad时出现一个峰值。

RADIOSENSITIVITIES OF CULTURED BARLEY OF DIFFERENT TYPE (Hordeum vulgare) |
| |
| Abstract: | The dormant seeds (with 13% moisture) of 47 barley varieties were irradiated with various doses (0-40 krad ) of 137Cs Y-rays.The radio-sensitivities of naked barley was significantly higher than that of hulled barley.The sensitive coefficients of seedling height were 0.04945 and 0.03667 for naked barley and hulled barley, respectively.The radiosensiti-vity of four-row naked barley was significantly higher than that of two-row hulled barley and six-row hulled barley.47 varieties studied could be divided into five types with different radiosensitivities, i.e.extreme resistant, resistant, intermediate, sensitive and extreme sensitive.It was also found that the dose-effect curves of cell nucleus volume had a pcak at 30 krad. |
