-
摘要: 水稻(Oryza sativa)核型分析结果:在12对染色体中,具中部着丝点的有5对,近中部着丝点的有6对(包括随体染色体),1对近端部着丝点。本文还着重讨论了随体的数目及所在的染色体。Abstract: The karyotype analysis based on mitotic cells in rice, Oryza sativa L.(2n=24), was conducted. Root tips were treated with KCl and enzyme and stained with Giemsa. Twelve pairs of chromosomes are arranged according to the length. The karyotype of rice analysed in this work is n =5m+6sm+1st and 2 pairs of satellite chromosomes were observed in numerous cells.
