摘要:

本文报道了我国特有植物白穗花(Speirantha gardenii(Hook.)Baill.,百合
    科)的体细胞染色体数目,并进行了染色体核型分析。取材于安徽黄山的白穗花
    为一个二倍体物种,它的体细胞染色体2n=38=22m+6sm+10st。其中第
    9对染色体为亚中部着丝点染色体,在短臂的近着丝点处具一次缢痕,是19对
    染色体中唯一的一对随体染色体。

Abstract:

 This paper reports the chromosome numbers and karyotype analysis of Speirantha
gardenii, which is endemic to China. The material was collected  from  Huang  Shan,
Anhui. It is a diploid species. Its somatic chromosome is 2n=38=22m+6sm+10st. The
9th pair is submedian centromere chromosomes, but it has two constrictions.  The se-
condary constriction is on the short arm near centromere. Of the 19 chromosome pairs,
secondary constriction is present only in this pair.
