【摘要】 研究了观赏植物花叶万年青属9个品种的组织培养和快速繁殖技术。不同品种的组织培养能力有很大差异。培养基中添加3～5 mg·L^-16-BA 比较适宜花叶万年青不定芽的诱导培养和增殖培养,生根培养基以1/2MS+0.5mg·L^-1 NAA 效果较好。实现了玛利安万年青等4个品种的组培快繁工厂化生产。更多还原

【Abstract】 Tissue culture and rapid propagation of 9 cultivars of Dieffenbachia were studied.The proliferation rates among the9 varieties were quite different.Treatment with 3-5 mg·L^-1 6-BA was favorable for adventitious shoot induction and plant prolif-eration.Treatment on 1/2MS medium with 0.5mg·L^-1 NAA was best for rooting.A large scale production of plantlets was estab-lished for 4 varieties,viz.D.maculata cv.Camilla,D.Maculata cv.Rudolph Roehrs,D.seguine cv.Wilson’s Delight and D.amoena cv.Mars.更多还原
