摘要: 采用常规压片法,对绿花百合(Lilium fargesii)、卓巴百合(L. wardii)、新疆百合(L. martagon
var. pilosiusculum)、台湾百合(L. formosanum)等4 种野生百合进行了染色体数观察和核型分析。结果表
明,绿花百合核型为3A,其余3 种材料核型均为3B。核型公式分别为:绿花百合2n = 24 = 4m + 8st
(4SAT)+ 12t;新疆百合2n = 24 = 4m(4SAT)+ 10st(2SAT)+ 10t;台湾百合2n = 24 = 4m(2SAT)+
4st + 16t(8SAT);卓巴百合2n = 24 = 2m(2SAT)+ 2sm + 8st + 12t(2SAT)。核型不对称系数分别为80.54%、
81.50%、81.78%和83.89%。

Abstract: The chromosome number and karyotype of four Lilium species with L. fargesii,L.
martagon var. pilosiusculum,L. formosanum and L. wardii included were analyzed. The results indicated
that the karyotype of L. fargesii was 3A,the others were 3B. The karyotype formulae were as the
following:2n = 24 = 4m + 8st(4SAT)+ 12t for L. fargesii,2n = 24 = 4m(4SAT)+10st(2SAT)+ 10t
for L. martagon var. pilosiusculum,2n = 24 = 4m(2SAT)+ 4st + 16t(8SAT)for L. formosanum and,
2n = 24 = 2m(2SAT)+ 2sm + 8st + 12t(2SAT)for L. wardii,and their asymmetry indexes(As. K%)
were 80.54%,81.50%,81.78% and 83.89% respectively.

Key words: Lilium, karyotype, asymmetry index
