Result It was found in the results that the better pretreatment time for onion root-tip was 3.0 h and its better dyeing solution was basic fuchsin dyeing solution. On this basis, it was found that the chromosome number of tested onion was 2n=2x=16 through chromosome karyotype analysis on the root-tip cells of onion.

结果］结果发现，洋葱根尖的较好的预处理时间为3.0 h，较好的染液为碱性品红染液；在此基础上，通过洋葱根尖细胞染色体核型分析，发现试验所用洋葱的染色体数为2n=2x=16。

MATERIALS AND METHODS: The root tips of Vicia faba were treated with different concentrations of sodium sulfite and sodium nitrite (in the concentrations of 25;50;100;200;400 mg/L) with distilled water as control for four hours.The root tips of Vicia faba were stained with carbol fuchsin and examined. The micronucleus rate and the rate of chromosome aberration were determined within root tip cells of Vicia faba.

材料与方法：用不同浓度的亚硫酸钠和亚硝酸钠(25、50、100、 200、400 mg/L)分别处理蚕豆根尖4 h，并以蒸馏水作为对照，用石炭酸品红染液染色，分别观察、测定蚕豆根尖细胞的微核率和染色体畸变率。
