铅诱导蚕豆根尖细胞微核及染色体畸变的研究
Effects of Pb2 +on Micronucleusn and Chromosomal Aberration of Vicia faba
摘要
Abstract
[Objective] The purpose was to study the effects of Pb2 +on the micronucleusn and chromosomal aberration of Vicia faba.[Meth-od] Vicia faba seeds were cultured with PbCl2 solutions at different concentrations, and distilled water treatment as control.The root tips were fixed, dyed and squashed for microscopic examination, and micronucleusn and chromosomal aberration of root tip cells were calculated.[Re-sult] When seeds were treated with 1.0 ×10 -4 -5.0 ×10 -4 mol/L Pb2 +from 4 days to 7 days,the micronucleusn and chromosomal aberration of Vicia faba increased successively with increasing Pb2 +concentration and treatment duration.[Conclusion] Pb2 +showed effects on the mi-cronucleusn and chromosomal aberration Vicia faba in a dose-and time-dependent manner.关键词
