Abstract

Abstract:

The karyology of 5 populations, all two species of Piptanthus (P.nepalensis and P.tomentosus) from Sino-Himalayas were studied in this paper, of which chromosome number and the karyotype of P.tomentosus was firstly reported. The results show that both species P.nepalensis and P.tomentosus share the same chromosome basic number x=9 and 2n=18, all of them are diploids. Statistical analyses show that there are evidently differences of karyotypes between the two species, that is, P.nepalensis belong to the 1A type, and P.tomentosus is the 2A type. In addition, there are some differences in karyotype among populations in P.nepalensis as well. These results are consistent with the anterior hypothesis by systematic and biogeography that P.tomentosus (with 2A) was resulted from the expansion and differentiation of P.nepalensis (with 1A ) from west to east during the himalaya uplift.
