植物核型分析是遗传、变异等研究的重要手段。本文通过对蚕豆核型分析的取材、预处理、固定、解离、染色、制片等技术环节的探索,并用不同浓度汞离子处理蚕豆根尖,结果表明,蚕豆染色体长度发生不同程度的变化,并阐述了汞胁迫对蚕豆染色体核型的影响。

The analysis of karyotype was a very important method to research the heredity and variation.In this paper,the sampling,pretreatment,stationary,dissociation,dye,squash and the effect of different concentration of Hg＋ on the chromosome karyotype of broad bean were studied.The result shows that,under different concentration of Hg＋,both the length of chromosome and the chromosome karyotype were changed.
