三褶虾脊兰的核型分析

The Karyotype Analysis of Calanthe triplicata

摘要:

采用压片法研究了三褶虾脊兰[Calanthe triplicata (Willem.) Ames]的染色体数目和核型。结果表明：三褶虾脊兰的染色体数目2n=38，为二倍体，核型公式为2n=2x=38=28m+8sm+2st。主要由中部和近中部着丝点染色体组成。核型分类为2B型，比较对称。

Abstract:

The chromosome number and karyotype of Calanthe triplicata was studied by applying fingertip pressing method. The results showed that the number of the somatic chromosome of Calanthe triplicata was 2n=38, and as diploid, its karyotype formula was 2n=2x=38=28m+8sm+2st. The diploid mainly consists of metacentric and submetacentric chromosomes. The karyotype belongs to 2B type.
