| Abstract: | Abstract This paper deals with the karyotype analysis of 3 species of Curculigo from China. The karyotype formulae are as follows:
1 ) C. crassifolia 2n= 2x = 18 = 10m(4SAT) + 8sm
2) C. capitulata 2n= 2x= 18 = 10m(2SAT) + 8sm
3) C. sinensis 2n=2x=18= 8 m(3SAT) + 10sm(2SAT)
Among them, the karyotype of C. sinensis S. C. Chen are reported for the first time. The karyotypes of 3 species of this genus fall into "2B" type, but the karyotype of C. sinensis might be more asymmetrical than C. crassifolia and C. capitulata based on their asymmetry indexes. |
