摘要
利用4龄起家蚕,添食不同浓度的Pb2+、Cd2+重金属离子,研究其对家蚕茧质和DNA损伤的影响。结果表明,受Pb2+、Cd2+影响,实验组家蚕的全茧量、茧层量、茧层率均低于清水对照组;凝胶电泳显示,DNA链发生明显的梯状断裂现象。
Damage of cadmium and lead to DNA chain and the effects on cocoon quality were studied in silkworm under exposure of different cadmium and lead concentrations. The result demonstrated that cadmium and lead both deceased the weights of all cocoon and cocoon shell and cocoon shell rate in the silkworm. In addition, other evidence showed that DNA chain was clearly broken into pieces and DNA band appeared obviously by DNA agarose gel eletrophoresis.
