摘要
利用Giemsa C-带方法对淡黄花百合(Lilium sulphureum Baker)进行了研究。结果表明:淡黄花百合(Lilium sulphureum)的染色体数目为2n=2×=24,每条染色体上都显示出特征带,带纹的深浅差异明显,其带型公式为:2n=24=2CI+2I+4CI++2CI++8I++2I+T++2IT++2I+N。染色体F有两条强弱不同的中间带和一条次缢痕带。通过Giemsa C-带方法可以将淡黄花百合(Lilium sulphureum Baker)的每条染色体区分开。
The chromosomes from root tips of Lilium sulphureum Baker were analysised by Giemsa C-banding. The result shown that, the karyotype is 2n-2x=24, and the different C-banding points were shown on each chro- mosome. The C-banding karyotype would be: 2n=24=2CI+2I+4CI++2CI^++8I^++2I+T++2IT++2I+N. Two different depth centromeric bands and one secondary constriction band were shown on chromosome F. Each chromosome of Lilium sulphureum Baker can be distinguished by Gemisa C-banding analysis.
