| Abstract: | The chromosome number of the Cercis yunnanensis Hu et cheng was counted by root tip squash method and the karyotype were analyzed. The result shows that the number of the Cercis yunnanensis Hu et cheng was 2n=2x=32,the karyotype formula based on Cercis yunnanensis Hu et cheng was K(2n)=32= 30m+2sm,which belong to "1 A" type of Stebbins karyotypic symmetry, and NF=64,As.K%=56.18%. |
