石蒜新核型及染色体数目在安徽的发现(英文)

A new chromosome number and karyotype in Lycoris radiata in Anhui Province

对安徽省马鞍山的石蒜居群进行了核型分析 ,发现了石蒜的一种新的染色体数目及核型。按Levan等 (1 964)标准 ,核型公式为 2n =2 4=6m +8sm +6st+4t,为 3A核型 (Stebbin,1 971 )。与目前国内外学者的观察结果差异很大。马鞍山居群的新染色体数目及核型均为首次报道。

Ma’anshan population of Lycoris radiata from Anhui was studied cytologically. A new chromosome number and karyotype were found for the first time. The karyotype of L.radiata was formulated as 2n=24=6m+8sm+6st+4t,belonging to Stebbin’s (1971) 3A type. This new karyotype and chromosome number of L.radiata were reported firstly in the world.
