- 摘要:
- 采用染色体常规制片法，结合显微摄影技术对沙米（Agriophyllum squarrosum (Linn.) Moq.）染色体进行检测分析。结果表明：沙米为二倍体，体细胞染色体数目为18；核型公式为2n=2×=18=14m+4sm，染色体相对长度组成为10M1+8M2，全组染色体长为24.09 μm，核型不对称系数（AS.K%）为58.86%，属于1A型；染色体总体积为85.95 μm3。
- Abstract:
- The chromosomes was tested and analyzed through normal method for preparing sides with the technique of microphotography.The results showed that the karyotype formula was 2n=2×=18=14m+4sm and belongs to ‘1A’ type of Karyotypic.The chromosome complement based on relative length formula was 10M1 + 8M2.The total length of all set of chromosome was 24.09 μm，the AS.K was 58.86%.The total volume of chromosome was 85.95 μm3.
