初生根长度对蚕豆根尖细胞微核率影响的研究

Effect of the length of root stalk on the micro -nuclei frequency in root-tip cells of Vicia faba

研究了不同长度蚕豆初生根微核率的差异,结果表明,初生根越短微核率越低,初生根越长微核率越高,提示蚕豆根尖细胞微核是可积累的,细胞分裂次数越多微核率越高,从而对蚕豆根尖微核测试的可靠性提供理论参考。

Effect of the length of root stalk on the micronuclei frequency in root-tip cells of Vicia faba was studied. The result showed that the longer the root was, the higher the micronuclei frequency was, and the shorter the root was,the lower the micronuclei frequency was. The reason might be that the micronuclei could be accumulated,and the more the cell division times were,the higher the micronuclei frequency was.
