The Karyotype Analysis of Fraxinus velutina

摘要: 应用根尖压片法对木樨科白蜡属绒毛白蜡(Fraxinus velutina)的染色体数目和核型进行了研究。结果表明:绒毛白蜡体细胞染色体数目为2n=22,核型公式为:K(2n)=22=20m+2 sm,属于"1A"类型。染色体相对长度组成为2n=22=4L+10M₂+8M₁。

Abstract: The number and karyotype of Fraxinus velutina chromosomes is researched,applying fingertip pressing flake method.The formula for karyotype:is reported in this paper.The number of Fraxinus velutina number of the somatic cell chromosome is 2n=22,which is K(2n)=22=20m+2sm and belongs to the type of "1A".The relative length of chromosome is 2n=22=4L+10M₂+8M₁.The purpose of this research is to provide foundations for the breeding and taxonomy.
