【摘要】 本文使用去壁、低渗、火焰干燥、Giemsa染色方法,制备水稻染色体标本,获得了我国产三种野生稻染色体核型,即:普通野生稻染色体核型为 K（2n）=24=2A^m+20B^5m+2^tC^5m;药用野生稻染色体核型为K（2n）=24=4A^m+18B^5m+2^tC^5m;疣粒野生稻染色体核型为K（2n）=24=6A^m+16B^5m+2^tC^5m。更多还原

【Abstract】 In this paper three different karyotypes of wild rice species growing in China were examined, after the preparation of chromosome sample by wall degradation, hypotonic treatment and flame-drying method and stained with Giemsa, i.e.,the karyotype of Oryza peres,his: K（2n） =24=2A^sm20B^sm+2^tC^sm; the karyotype of O. officinalis: K（2n）=24=4A^m+18B^sm+2^tC^sm; the karyotype of O. meyeriana: K（2n） =24=6A^m + 16B^sm+2^tC^sm.更多还原
