| Abstract: | Ten species of the genus Dendranthema are cytologically studied. The karyotypes and chromosome numbers of D. dichrum (2n=2x=18=14m + 4sm and 2n= 4x=36=28m+6sm +2st), D. argrophyllum (2n=6x=54 = 38m + 14sm + 2st ), D. naktongense (2n=2x=18=10m + 8sm and 2n=8x=72= 50m + 14sm + 8st ) and new chromosome number record of D. mongolicum 〔2n=2x=18=12m + 2sm + 4st (2SAT)〕 are reported for the first time. Previous works have been taken into account,and the karyotypic characters and evolutional trend of Dendranthema are discussed. |
