| 摘 要： | 本文研究了甘肃萱草属6种、1变种的染色体核型;黄花菜K(2n)=22=12m+10sm(2SAT);小黄花菜K(2n)=22=10m+12sm;北萱草K(2n)=22=8m+14sm;北黄花菜K(2n)=22=14m+6sm+2st;萱草K(2n)=22=12m+8sm+2st;重瓣萱草K(2n)=33=18m+12sm+3st:折叶萱草K(2n)=22=10m+10sm+2st。以上核型可自然地分成两大类群,第一类群包括小黄花菜、北萱草、黄花菜;第二类群包括折叶萱草、萱草、重瓣萱草、北黄花菜。

| Abstract: | The present paper deals with the results in karyotypes studies of6 species and 1 variety of Hemerocallis in Gansu. The karyotype formulas are follows:H. citrina K (2n)=22=12m+10sm (2SAT): H. minor K (2n)=22=10m+12sm; H.esculenta K (2n)=22=8m+14sm; H. lilio-asphodelus K (2n)=22=14m+6sm+2st; H.fulva K (2n)=22=12m+8sm+2st: H. fulva var. kwanso K (2n)=33=18m+12sm+3st;H. plicata K (2n)=22=10m+10sm+2st.In these studies, the karyotypes of the 6species and 1 variety can be divided naturally into two groups. The first groupconsists of H. minor, M. esculenta and H. citrina. The second one includes H. plicata,H. fulva, H. fulva var. kwanso and H. lilio-asphodelus. |
