| 摘 要： | 以不同浓度的垃圾渗出液为诱变剂,测定蚕豆根尖细胞的有丝分裂指数、微核率和染色体畸变率。结果表明:垃圾渗出液能够降低蚕豆根尖细胞有丝分裂指数,能诱发较高频率的微核和染色体畸变,产生染色体断片、滞后染色体和染色体桥。随着垃圾渗出液处理浓度的增加,有丝分裂指数降低,而微核率和染色体畸变率均升高;随着垃圾渗出液浓度的进一步增加,染色体畸变率却下降,但仍明显高于对照组。

| Abstract: | With different concentrations of refuse leachate as mutagen,the mitotic index,micronucleus frequency and chromosome aberration frequency of Vicia faba Root-tip Cells are determined.by micronucleus assay and chromosome aberration assay.The results indicated that the cell mitotic index in Vicia faba root tip cells should be decreased by refuse leachate,while a higher frequency of either micronucleus or chromosome aberration and chromosomal segments,bridges and laggards should attain.The cell mitotic index decreased when the concentration of refuse leachate increases in a certain range,however,the frequency of micronucleus and chromosome aberration could increase,but an increase in the exceeding range should lead to a decrease of the chromosome aberration frequency which is still higher than the control group. |
