| 摘 要： | 本文研究了除草通对玉米幼苗初生不定根根尖细胞有丝分裂的影响。结果表明，除草通是一种影响细胞有丝分裂的除草剂，其作用方式在于阻止分生组织细胞从前期向中、后、末期的过渡，引起染色体凝集、短缩以及多核、多核仁等一系列畸形与异常变化。

| Abstract: | The effect of pendimethlin on cell mitosis of maize seedling advantitious root tip was studied inthis paper.The results showed that pendimethalin is a herbicide interfering cell division,The mito-sis of pendimethalin treated root was arrested at metaphase with contracted and condensed chromo-somes and produced a series of abnormal,polymorphic cells such as multinucleate,multinucleolus,micronucleus and polyploid cells. |
