花叶万年青的组织培养和快速繁殖

TISSUE CULTURE AND RAPID PROPAGATION OF DIEFFENBACHIA

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^-1 6-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＋0.5 mg 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。

Abstract:

Tissue culture and rapid propagation of 9 cultivars of Dithenbachia were studied.The proliferation rates among the 9 varieties were quite different. Treatment with 3-5 mg L^-1 6-BA was favorable for adventitious shoot induction and plant proliferation. Treatment on 1/2 MS medium with 0.5 mg L^-1 NAA was best for rooting. A large scale production ofplantlets was established for 4 varieties, viz. D. maculata cv. Camilla, D. Maculata cv.Rudolph Roehrs, D. seguine cv. Wilson's Delight and D. amoena cv. Mars.
