With the root tips of germinated Angelica sinensis seeds treated with GA3 as materials, karyotype analysis was performed by photomicrographic technology and conventional chromosome preparation method. The results showed that the chromosome number of A. sinensis was 2 n=2.2, which accords with previous studies; and no satellites were observed, and the chromosome karyotype was 2A, with the asymmetrical karyotype coefficient （AS.K%） of 54：85%. The total length of the chromosomes was 113.4 pro, and total volume of chromosomes was 83.21 μm3.展开更多
