摘要:

用数量分类技术比较研究了国产萱草属植物的核型。所研究的分类群是:Hemerocallis citrina,
H.dumortieri,H.esculenta,H.forrestii,二倍体和三倍体H.fulva,H.lilioasphodelus,H.mid-
dendorffii,H.minor,H.multiflora,H.plicata。结果表明,物种形成已发生在染色体水平,染色体
变异与形态变异基本一致。结果支持将H.citrina和H.minor作为H.lilioasphodelus的亚种,H.
esculenta作为H.dumortieri的变种。结果不支持将H.middendorffii作为H.dumortieri的变种,也

没有发现H.multiflora与H.plicata密切相关的证据。

Abstract:

Comparative studies of karyotypes in Hemerocallis from China have been carried
out using numerical techniques. Taxa studied are as follows: Hemerocallis citrina, H. du-
mortieri , H. esculenta , H. forrestii , di- and triploid H. fulva , H. lilioasphodelus , H.
middendorffii, H. minor, H. multiflora and H. plicata. The results show that varia-
tion in speciation has taken place at chromosomal level, and that karyotype variations have
largely paralleled the morphological ones. Taxonomic proposals are given to treat H. citrina
and H. minor as subspecies of H. lilioasphodelus, and H. esculenta as a variety of H.
dumortieri. The results are not in favour of considering H. middendorffii as a variety of
H. dumortieri, and H. multiflora closely related to H. plicata.
