| Abstract: | Objective] The chromosome number and karyotype in Chinese date Goutouzao were studied.Method] Taking the young shoot tips of Chinese date Goutouzao as the experimental materials,chromosome were observed by digestion of the cell wall with enzyme.Result] The better mitotic phase was obtained after dyeing by improved stained magenta.Conclusion] The chromosome number of Goutouzao was 2n=24.Karyotype type was 2B,and karyotype formula was 2n=2X=24=5 m 5 sm 2 st. |
