朱顶红鳞茎芽诱导快速繁殖技术研究

Propagation of Bulb Bud Induction of Amaryllis vittata

为研究朱顶红丛芽诱导快速繁殖技术,以朱顶红鳞茎切块为外植体,对影响鳞茎芽增殖、继代及生根进行了研究,建立了其再生体系。结果表明,MS+NAA0.5mg/L+6-BA4.0 mg/L+2,4-D 2.0 mg/L培养基是最佳芽增殖培养基,MS+NAA0.5 mg/L+6-BA2.0 mg/L+活性碳1 g/L是最佳继代培养基,MS+6-BA1.0 mg/L+NAA0.3 mg/L+活性碳1 g/L是最佳生根培养基。

The efficient method for bulb cutting blocks on bulb bud proliferation, subculture and rooting was studied.The results showed that MS+NAA0.5 mg/L+6-BA4.0 mg/L+2,4-D 2.0 mg/L was the best bud proliferation medium,MS+NAA0.5 mg/L+6-BA2.0 mg/L+ 1g/L activated carbon was the best subculture medium, and MS+6-BA1.0 mg/L+NAA0.3 mg/L+ 1 g/L activated carbon was the best rooting medium.
