摘要
应用蚕豆根尖微核试验,对甲醛的遗传毒性效应进行了研究。结果表明:两种蚕豆根尖细胞对空气中的甲醛非常敏感。当甲醛处理浓度为2.85mg/m3时,蚕豆根尖细胞微核率就明显高于对照,达极显著差异水平。随着甲醛处理时间的延长,蚕豆幼根细胞微核率明显升高,微核率与处理时间之间呈现明显的正相关关系。松滋青皮蚕豆根尖细胞对甲醛污染的敏感性高于普通蚕豆。
The micronucleus （MCN） test of horsebean （Vicia faba） root tips is conducted to study genetic toxicity of formaldehyde pollution, showing horsebean＇s root tips are extremely sensitive to formaldehyde in air. With prolonged exposure of the horsebean to formaldehyde, MCN of its root tip cells significantly increases, indicating MCN rate is positively correlated to the exposure time. Additionally, it is found root-tip cell of Songzi Green Vicia faba is more susceptible to formaldehyde than that of local common horsebean.
