摘    要:利用骨髓细胞蒸气固定法制备染色体标本,研究了福建大头蛙(Limnonectesfujianensis)黄山居群的核型、C 带和Ag NORs。结果表明,福建大头蛙核型为2n =2 2 =2 0M 2SM ,NF =44,次缢痕位于No 1 0q ;各染色体均有着丝粒C 带,3p、9q出现插入型C 带;Ag NORs位于1 0q。

关 键 词:福建大头蛙  大头蛙  核型  C-带  Ag-NORs

Abstract:The chromosome samples were prepared from metaphase marrow cells from Limnonectes fujianensis which distributes in Yellow Mountain by stream-fixation method. Then the karyotype, C-band and Ag-NORs of L. fujianensis were studied. The chromosome number of L. fujianensis is 2n=22(20M 2SM). All the chromosomes are metacentric or submetacentric(NF=44), and the secondary-construction(SC) chromosome is No.10. Each chromosome has a centromeric C-band, and there are inserted C-bands in both the short arm of No.3 chromosome and the long arm of No.9 chromosome. Ag-NORs are localized in the long arms of the No.10 pair.
Keywords:Limnonectes fujianensis  L  kuhlii  Karyotype  C-band  Ag-NORs
