本文用植物细胞遗传学方法,对几种工厂污水和有毒气体可能引起植物细胞染色体损伤进行了初步研究,并确定美国紫露草为敏感的植物.美国紫露草对含酚、含铬等污水及二氧化硫气体均有明显反应,通过镜检可观察到染色体桥,落后染色体、染色体环和染色体膨胀等畸变类型,结果认为后期侨和四分体微核的统计分析可作为方便有效的监测指标.最后讨论了本方法在监测环境污染程度上的应用.
In this paper, plant cytogenetics method, plant effluents and toxic gases may cause plant cell chromosome damage was initially studied and to determine the United States of Ametropia as sensitive plants .American purpleFlowers containing phenol, chromium and other sewage and sulfur dioxide gas are There is a clear reaction, through the microscopic examination can be observed in the chromosome bridge, backward chromosomes, chromosome ring and chromosome dilation and other types of distortion, the results that the post-Qiao and quadruple micronuclei statistical analysis can be used as a convenient and effective monitoring indicators.Finally discussed the Method in monitoring the degree of environmental pollution.
