Abstract: Shoots in vitro of different color flower of three popular Doritaenopsis varieties, the yellow flowers of Dtps.Chain Xen Queen, the red flowers of Dtps.Jiuhbao Red Rose, and the white flowers of Dtps.[I-Hsin Actor×(Tom Boy×Mount Beauty)]were used as materials and the effects of basic culture media and organic compounds on rooting and growth of these shoots were investigated.It was found that Dtps.Jiuhbao Red Rose rooted and the leaves grew better in Kyoto than in 1/2 MS, while the leaves of Dtps.Chain Xen Queen grew well in Kyoto.All the three varieties rooted better in the media that added with 100 g/L banana.The leaves of Dtps.Chain Xen Queen grew better in the media supplemented with 70 g/L banana and 30 g/L potato.

摘要： 研究不同基本培养基及有机添加物对3个品种朵丽蝶兰组培苗生长的影响。实验表明,朵丽蝶兰红花品种(Doritaenopsis Jiuhbao Red Rose)在以花宝1号作基本培养基的处理中,根粗、根长和叶长、双叶幅明显优于1/2 MS培养基;花宝1号培养基也利于黄花品种(Dtps.Chain Xen Queen)组培苗的叶片生长;添加香蕉泥100 g/L有利于3个品种即红花、黄花品种及白花红心品种Dtps.[I-Hsin Actor×(Tom Boy×Mount Beauty)]的根系生长,而添加香蕉泥70 g/L+马铃薯30 g/L仅有利于黄花品种的叶片生长。
