Abstract

Taking treated tender buds in germination stage as experimental materials，the karyotypes of Clerodendrum trochotomum Thumb. from 14 provenances were observed by the conventional sheeting method. The results indicated that all the chromosomes of the 14 provenances were diploids and attributed to small chromosomes，with an absolute average length of 1.45 m. There were 5 types of chromosome karyotypes classified from the morphological observation：2n = 2x = 36 m + 16 sm，2n = 2x = 40 m + 12 sm，2n = 2x = 44 m + 8 sm，2n = 2x = 46 m + 6 sm and 2n = 2x = 48 m + 4 sm，respectively，and there was no satellite found in all the karyotypes. The karyotypes of all the provenances showed a morphological similarity，with karyotype type of 2B，except the 021 provenances of 2A type.［Ch，2 fig. 3 tab. 22 ref.］
