Abstract:
This paper reported the chromosome numbers and karyotypes of seven species of
Fritillaria L.from Anhui Province.The results were shown as:(1)
F.thunbergii:2n=24=4m+20t(1SAT);(2)
F.monantha:2n=24=4m+20t+3Bs;(3)
F.huangshanensis:2n=24=4m+20t(1SAT);(4)
F.ningguoensis:2n=24=4m+20t(2SAT);(5)
F.xiaobeimu,2 cytotypes:TypeⅠ,2n=25=2m+2sm+4st+16t(1SAT)+1Bs,TypeⅡ,2n=24=2m+4sm+2st+16t(2SAT);(6)
F.qimenensis:2n=24=2m+2sm+6st+14t;(7)
F.anhuiensis:2n=24=2m+2sm+2st+18t.Except two cytotypes of the
F.xiaobeimu,belonging to "3C",the karyotypes of the other species belonged to"3B".The karyotypes and chromosome numbers of the
F.huangshanensis and
F.monantha from Anhui in this paper were studied for the first time.Compared to the results from the former,the karyotypes of
Fritillaria L.from Anhui Province are polymorphic,different karyotype formulae for the
Fritillaria L.in Anhui Province were reported in differ-(ent) studies.
