摘要
采用染色体常规制片法,结合显微摄影技术对罗布麻染色体进行检测分析。结果表明:罗布麻染色体数为2n=14,核型公式是2n=14=6M+2m+4sm(1SAT)+2T,全组染色体总长度为35.92μm,长臂总长为21.92μm,核型不对称系数(AS.K%)为60.97%,总体积为15.19μm3。
The chromosomes were tested and analyzed through normal method for prepearing slides with the technique of microphotography. The results showed that the chromosom number of Apocynum Venetum Linn. was 2n= 14. The formula of karyotype was 2n=14=6M+2 m+4 sm(1SAT)+2 T. The total length of all set of chromosomes was 35. 92 μm and the total length of long arms was 21.92μm. Asymmetric coefficient of karyotype was 60. 97 %. The total voluem was 15. 19μm^3.
