摘　　要：采用常规骨髓细胞空气干燥法 ,研究了贵州 5种菊头蝠的核型。贵州菊头蝠和中菊头蝠 2n =62 ,两者染色体臂数 (NF)均为 60 ;托氏菊头蝠、小菊头蝠和栗黄菊头蝠的染色体数是 2n =3 6,其中托氏菊头蝠和小菊头蝠染色体臂数 (NF)是 5 8,栗黄菊头蝠是 60。 5种菊头蝠的性别决定机制均是XY。The karyotypes of five Rhinolophus species from Guizhou were studied by means of bone marrow cell and air\|dried preparations. Rhinolophus rex and R.affinis have a diploid chromosome number of 62,and a fundamental number (FN) of 60. The diploid number of R.thomasi, R.blythi and R.rouxi is 36,among which R.thomasi and R.blythi have a fundamental number (FN) of 58 and R.rouxi a fundamental number of 60. The sex determination of the five species is XY.
