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.
