摘  要:
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.
