吲哚乙酸、萘乙酸对蚕豆根尖细胞微核的诱导作用
Effects of IAA and NAA on micronucleus in the rip cells of Vicia faba root
摘要
Abstract
In order to study the genetic toxicity induced by indole-3-acetic acid (IAA) and 1-naphthlcetic acid (NAA) ,the root-tips of Vicia faba were exposed to the different concentrations of IAA and NAA(1,3,5,7,10,20,40,60,80,100mg. /L) for 6,12,24h to investigate the effect of IAA and NAA on mitosis index (MI), micronucleus rate (MCN),and chromosomal aberration rate(CAF). The results showed that when the concentration was low, compared with the control group, MI, MCN and CAF all increased , with an good relationship between the dosage and the effect. When the concentration was higher, MCN and CAF were negatively correlated with MI. MCN of the treated group significantly differed from the control group(P<0. 05 or P<0. 01). These results suggested that IAA and NAA could induce genotoxic effect on the rip cells of Vicia faba root.关键词
