The karyotypes of two Ficus species, Ficus religiosa Linn, and Ficus microcarpa L. F. Were examined by root tip squash method. The results indicated that the chromosome numbers of the two species were2n = 30. The karyotypes were IB for both of them, the karyotype formula was 2n = 2x = 30 = 24m (2SAT)+6sm for F.religiosa Linn, and 2n = 2x=30 = 28m(2SAT) +2sm for F. Microcarpa L. F.. Comparatively.the karyotypes of these two species were similar and genetically close;The karyotype asymmetries ranked in the increasing order of F. Religiosa Linn, and F. Microcarpa L. F. ,and the karyotype of F. Microcarpa L. (. Appeared more primitive. The formula for two Ficus species were analyzed for the first time.
