攀援天门冬染色体核型分析

摘要

The number and karyotype of the chromosome of Asparagus brachyphyllus Turcz.were studied.The results show that the chromosome number of the species is 2n=20 and its karyotype formula is K (2n)=20=2M+14m+4sm,belongs to type "1B" of Stebbins' karyotype symmetry.%试验对攀援天门冬体细胞染色体进行了核型分析,结果表明,其染色体数目为2n=20,核型公式为k(2n)=20=-2M+14m+4sm,核型为"IB"型.
