| 摘 要： | 对蚕豆根尖组织进行了南湖区域医疗废水、工业废水,实验废水及生活污水等多种不同来源的典型污染水样暴露试验,通过常规染色压片技术对蚕豆根尖细胞的有丝分裂过程进行检测,探查南湖区域不同污染水体对蚕豆根尖细胞有丝分裂期染色体的影响。结果表明:不同污染程度的废水均能使细胞的生长受到明显的抑制,对染色体产生不同程度的影响;同时细胞还出现微核、异常染色体产生不均衡的多极移动分布、染色体片段、染色体桥及环状染色体等异常现象。

| Abstract: | The root tips of Vicia faba were treated with the hospital filthy water,industrial wastewater and domestic sewage from South Lake.Through normal squashed specimen,the effect on mitosis process of the root tip cells of Vicia faba was investigated.The result showed that the growth of cells was restricted obviously after the treatment and the chromosomes was affected at a certain level.Micronucleus,the multi-polar distribution of chromosomes,chromosomal bridges,loops,fragments and some other abnormal phenomena appeared in Vicia faba root tip cells with different treatments. |
