摘 要 ：对亚铁杂交百合红芯Fangio，进行了染色体数目、花粉母细胞减数分裂行为和染色体核型研究，结果表明：红芯为三倍体，染色体数为2n=3x=36；花粉母细胞减数分裂异常；染色体组成为：R(2n)=3x= R(2n)=3x=12m(SAT)+3sm+3sm(SAT)+12st+3st(SAT)+3t，在第2、4、8、9、10、12染色体上有随体，其核型分类属于3B 型。用不同浓度秋水仙素对其试管苗和鳞片处理不同时间，均对诱导红芯百合染色体加倍有效,最高变异率达20%以上，部分变异苗为六倍体。

Abstract:Meiosis of megaspore and karyottype were studied in Longiflorum-Asiatic Lily “Fangio”. the results showed that Meiosis of megaspore of lily “Fagio” is abnormal, the chromorome number of lilium“Fagio” is 2n=3x=36,the chromorsome composition is R(2n) =3x=R(2n) =3x=12m(SAT) +3sm+3sm(SAT) +12st+3st(SAT) +3t.There are subsidiacy bodies on the second,fourth,eighth,ninth,tenth,twelfth belongs pair of chromorome. Its karyoty is 3B type in Taxonomy. Scales and plantlet in vitro of Lily “Fangio” was treated with colchicine at different concentrations and time. The highest induction frequency (20%) some of them are sextuploid.
