| 摘 要： | 利用Giemsa C-带方法对宜昌百合（Lilium leucanthum(Baker) Baker）进行研究。结果表明：宜昌百合（L. leucanthum）的染色体数目为2n＝2x=24，单套染色体的条带总数目为21条。其带型公式为：2n＝24＝6C+2CI+2I+2CI++2CI++4I++2I++2T++2I+S。宜昌百合（L. leucanthum）每条染色体上都显示出显著的特征带，且带纹的深浅差异明显。宜昌百合（L. leucanthum）的强带主要集中在着丝点及附近区域。通过Giemsa C-带方法可以将宜昌百合（L. leucanthum）的每条染色体区分开。

| Abstract: | The chromosomes from root tips of Lilium leucanthum(Baker)Baker were analyzed by Giemsa C-banding.The result showed that,the karyotype is 2n=2x=24,the banding number of one genome was 21.The C-banding karyotype would be:2n=24=6C+2CI+2I+2CI++2CI++4I++2I++2T++2I+S.Significantly different C-banding points were shown on each chromosome.Most of the strong bands of L.leucanthum were distributed on the centromeric regions of the chromosomes.Each chromosome of L.leucanthum(Baker)Baker can be distinguished by Giemsa... |
