Study on Karyotypes of Four Species in Lysimachia

  • 摘要: 对珍珠菜属4种植物的核型进行了研究。结果表明,叶头过路黄(Lysimachia phyllocephala Hand.-Mazz.)的核型为:2n=2x=24=2m+6sm+2st+14t,茂汶过路黄(L. stellarioides Hand.-Mazz.)的核型为:2n=2x=24=4m+2sm+18t,均属首次报道。矮桃(L. clethroides Duby)的核型为:2n=2x=24=16m+8sm(1SAT),腺药珍珠菜(L. stenosepala Hemsl.)的核型为:2n=2x=24=10m+12sm+2st,与前人报道的有所不同。还对该属已报道的23种植物的核型进行了比较。
    Abstract: Karyotypes of 4 species in Lysimachia were investigated.The chromosome mumbers and karyotypes of two species,namely,Lysimachia phyllocephala Hand.-Mazz.(2n=2x=24=2m+6sm+2st+14t)and L.stellarioides Hand.-Mazz.(2n=2x=24=4m+2sm+18t),are reported here for the first time.The other two species,L.clethroides Duby((2n=2x=24=16m+8sm(1SAT))and L.stenosepala Hemsl.(2n=2x=24=10m+12sm+2st),are slightly different from those previously reported.At the same time,we summarized the characteristics of karyotypes in Lysimachia on the basis of the available data for 23 species.
