| Abstract: | Karyotypes of five species of Cycas were studied.The results showed that the numbers of chromosomes of five Cycas species were 2n=22; C.micholitzii :2n=22=4m 4sm 2st 12T; C.multipinnata :2n=22=4m 4sm 2st 12T; C.revoluta :2n=22=4m 6sm 12T; C.taitungensis :2n=22=4m 6sm 12T; C.taiwaniana :2n=22=4m 4sm 2st 12T.The variation and evolution of karyotypes in Cycas were also discussed in this paper. |
