| 摘 要： | 采用常规压片法和改良BSG法对3个居群白木香的染色体核型及Giemsa C-带带型进行研究。结果表明:3个居群白木香的核型均属2B类型,其中广西居群白木香的核型公式为2n=16=4m+8sm+4st;其他两个居群白木香的核型公式为2n=16=6m+6sm+4st,居群间核型变异不明显。白木香的C带带型为CIT型,具有着丝粒带、中间带、端带和全带。3个居群白木香C带的分布、数目和类型不完全一样,出现了带型的多态性。

| Abstract: | For the first time,a conventional analysis of chromosome karyotype and Giemsa C-banding was carried out in three populations of Aquilaria sinensis.Three populations showed same chromosome number of 2n=2x=16 and the asymmetry of the karyotype was categorized as type 2B.The variance of karyotype was not obvious in three populations,only karyotypical formula(2n=16=4m+8sm+4st) in one population was different from the other two(2n=16=6m+6sm+4st).The Giemsa C-banding pattern of A.sinensis was CIT pattern.Within G... |
