摘要
以兰州百合的鳞片、叶片、根的不同部位为外植体成功获得再生植株,并建立了快速无性繁殖体系。在组织培养中不同外植体不同部位在培养时诱导分化能力是不同的。本试验以MS为基本培养基加不同的植物生长调节剂配比进行培养,发现不同外植体不同部位分化能力存在差异,其差异由强到弱为:鳞片、根、叶片。同时鳞片不同部位的分化能力由强到弱为:下>中>上,叶片不同部位的分化能力由强到弱为:叶片基部>中部>叶尖,根的不同部位分化能力由强到弱为:根基部>根尖>根中部。
The Effects of Lilium davidi The clonal propagations of Lilium davidii var. Unicolor were developed through culture of different parts of scale, leaves and roots respectively in vitro. The different explants and parts on the culture media hone influence to the inducement of the bulb of lily. This experiment develops the liquid with the MS culture anedium ＋ the different hormone of certain ratio to carry on the development , to find out the ability of differentiation on the different explants and parts , in proper order, from the strong to feeble： The scale 〉 root 〉 leaf. At the same time,to find out the ability of differentiation on the different parts. The scale were as follows ： lower part 〉 median part 〉 upper part. The leaf were as follows ： the base of leaf 〉 median part 〉 leaf apex. The root were as follows-the base of root 〉 root apex 〉 median part.
