摘要

20个不同类型栽培大麦品种的休眠种子，用

137

射线照射后，研究其细胞核体积与辐射敏感性的关系。实验结果表明，细胞核体积的剂量效应可用线性方程：

拟合，幼苗生长抑制的剂量效应用方程

拟合。不同类型栽培大麦的细胞核体积剂量效应差异不显著，核体积与核体积的

呈显著负相关（

），与幼苗生长抑制的

无明显相关。

Abstract

After dormant seeds of 20 barley varieties were irradiated with

137

-rays

the correlation of cell-nucleus volume and radiosensitivity were studied. The results showed that the dose-effect of cell-nucleus volume could be fitted by a linear regression equation y=A+Bx

and the dose-effect of seedling growth inhibition be fitted by equation

(

) =1- (1-

)

. No clear difference was found in dose-effect of nucleus volume among different types of barley. The value of nucleus volume was significantly correlated with that for nucleus volume D

among varieties (

=-0.8828

) . There was no obvious correlation among the D

values for nucleus volume and for seedling growth inhibition.
