为研究汉江武汉市城区段水质变化对蚕豆根尖细胞的遗传毒性效应,于汉江流经武汉市东西湖区至其与长江的入江口之间设置水样采样点,采用蚕豆根尖微核技术,研究在不同水样胁迫下对蚕豆根尖的生长和对基因组 DNA 的遗传毒性效应.结果表明,与对照组蒸馏水相比,不同水样处理后均可显著抑制蚕豆根尖的生长速度,其对蚕豆根尖生长的抑制率范围为0.37%～0.75%;除样点 C 外,不同水样处理后根尖恢复生长速度与对照组均无显著差异.不同水样处理蚕豆根尖细胞后,在细胞有丝分裂的不同时期发现有染色体畸变和微核的形成.统计分析表明,不同水样可显著诱导蚕豆根尖细胞形成微核,且沿汉江至长江交汇处各样点水样处...

The genotoxicity effect of water on the root tip cells of Vicia faba was carried out.Water sam-plings were collected from Dongxihu district of Wuhan to the entrance into the Yangtze River along Han-jiang river.Genotoxicity effects of water stress on growth and genome DNA of the root tip cells were ana-lyzed by using micronucleus test of V.faba root tips.Compared with the control of the distilled water,the results showed that water samplings could significantly inhibit the growth of V.faba root tips with the in-hibition rate of 0.37%to 0.75%.Exc...
