二甲戊灵对玉米根尖细胞有丝分裂的影响
Effect of Herbicides Pendimethalin on Chromosome Aberration of Corn Root Tip Cells
摘要
Abstract
[ Objective ] The aim was to explore the effects of different concentrations and different treatment time of pendimethalin on chromosome aberration of corn root tip cells. [ Method] Corn root tips were treated with 0.02,0. 10 and 0.20 g/L pendimethalin,and then effects of different concentrations of pendimethalin on chromosome aberration of corn root tip cells were observed after treatment of 12,24,36 and 48 hours. [ Result ] It was observed through microscope that chromosome condensation and multipolar were main phenomenon, accompanied by bridges, rings,laggards,chromosome doubling and micronuelei. Both different concentrations and different treatment time of pendimethalin could induce corn root tip cells to abnormal division, among them 0.10 g/L pendimethalin and the treatment time of 24 h could induce the highest aberration rate of chromosome (7.389% ). [Conclusion] The research provides reference for the rational use of herbicides pendimethalin.关键词
