| 摘 要： | 蚕豆根尖微核率（ＭＣＷ）、染色体畸变率（ＣＡＦ）与重金属离子间有明显的效应－剂量关系。在较低剂量情况下，两者呈直线回归；在较高条件下，据本实验（采用Ｐｈ和Ｈｇ）结果，随处理浓度的提高，其关系曲线为“Ｍ”形。通过对聚丙烯酸胺过氧化物同功酶电泳的结果及前人成果分析，认为这与同工酶变化及抗性酶活性有关。另外，对于Ｐｂ、Ｈｇ处理，间期ＭＣＮＦ，中期ＣＡＦ和后期ＣＡＦ随浓度的升高并不同步达到最大值，即中期ＣＡＦ与剂量的线性区段长于其他两者。

| Abstract: | s:The relation between MCNF,CAF and heavy ion was studied.The results showed that at lower dose the both appear linear regression;and at higher dose(Pb, Hg) the both appear "M" shape.Analyses of peroxidase isogymes showed that relation between MCNF, CAF and heavy ion is interrelated activity of isogyme and resistant engyrne |
