摘要

测定了紫露草02号无性系雄蕊毛粉红色突变的增氧率。这些是针对X射线(OER为3.2)和中子在0.395至13.4-MeV的六种能量(OER范围为1.32至1.68)下测定的。与RBE不同,OER值仅显示出对中子能量的轻微依赖性,并且没有发现随剂量变化。我们的结果似乎与其他系统普遍报道的OER一致,但在某些能量下与之前报道的紫露草的结果不一致。

Oxygen enhancement ratios (OERS) for somatic mutations in tradescantia stamen hairs

Oxygen enhancement ratios (OERs) were determined for pink mutations in stamen hairs of Tradescantia clone 02. These were determined for X-rays (OER of 3·2) and neutrons at six energies ranging from 0·395 to 13·4-MeV (OERs ranging from 1·32 to 1·68). Unlike RBE, OER values showed only a slight dependence on neutron energy and were not found to vary as a function of dose. Our results appear consistent with OERs generally reported from other systems, but at certain energies do not agree with results previously reported for Tradescantia.
