摘要
报道了吉林省产5种百合科植物的染色体数目和核型:①毛百合LiliumdauricumKer.-Gew1.2n=24=2m(2SAT)+2sm(28AT)+8st(2SAT)+12t(2SAT);②有斑百合L.concolorSalisb.var.buschianum(Lodd.)Baker2n=24=2m(2SAT)+4sm(4SAT)+6st(2SAT)+12t;③兰州百合L.davidiiDuch.var.unicolor(Hoog.)CoHon.2n=24=2m(2SAT)+2sm+4st(2SAT)+14t+2T;④朝鲜百合L.amabilePalib.2n=24=2m+2sm(2SAT)+10st(4SAT)+10t:⑤卷丹L.lancifoliumThunb.2n=3x=36=6m+12sm+12st(1SAT)+6t。讨论了核型特点及近缘关系等,其中②、③、④的染色体核型为首次报道。
The chromosome numbers and karyotypes of 5 species in Lilium L. from Jilin Province were studie. The result shows①Lilium dauricum Ker. Gawl. 2n=24=2m(2SAT)+2sm(2SAT)+8st(2SAT)+ 12t(2SAT);②L.concolor Salisb. Var. buschianum (Lodd.)Baker2n= 24= 2m(2SAT)+4sm(4SAT)+6st(2SAT)+12t;③L. davidii Duch.Var.unicolor (Hoog)Co Hon, 2n=24=2m(2SAT)+2sm+4st(2SAT)+14t+2T;④L. amabile Palib.2n=24=2m+2sm(2SAT)+10st(4SAT)+10t;⑤L. lancifolium Thunb. 2n (3x) =36= 6m+ 12sm+12st(ISAT)+6t. At the same time,the characteristics of the karyotypes and relationships of these species are discussed in the paper, among them the chromosome karyotypes of②,③ and ④ are reported firstly.
