| 摘要: |
| 利用改良的Giemsa C带技术,分析鹅观草(Roegneria kamoji)的染色体C带带型。结果鹅观草根尖细胞染色体数目为42,其染色体的相对长度为2.99%~6.89%,臂比1.00~1.67,Giemsa C带核型是:2n=6x=42=40m+2M。不同染色体之间的C带带型在带的数量、大小、强弱及位置等方面存在明显差异。认为C带可作为鹅观草染色体的细胞学标记。 |

| Abstract: |
| The Giemsa C-banding analysis of Roegneria kamoji is carried out by using an improved C-banding procedure. The karyotype formula is 2n=6x=42=40 m+2 M. The relative length of chromosome is 2.99% to 6.89%,the arm ratio is 1.00 to 1.67. The C-banding patterns in number,size,dyeability and distribution among chromosomes are distinctively different. The C-banding pattern is regarded as a cytological marker of all chromosomes of R. kamoji. |
