药用杭菊扦插育苗技术研究

目的 探索适合杭菊扦插繁殖的条件.方法 考察质量浓度分别为250、500、750、1000 mg/L的吲哚乙酸(LAA)、萘乙酸(NAA)、吲哚丁酸(IBA)对杭菊2个不同部位的插穗扦插的影响.结果 嫩梢和茎段扦插的生根数分别为13.63和5.96,根系效果指数分别为3.13和1.4.采用激素处理过的插条生根效果显著好于对照,其中以750 mg/L IBA处理后的生根效果最好,生根效果指数为17.8.结论 本研究为杭菊的扦插繁殖提供参考.

Study on cutting propagation techniques of medicinal Chysanthemum morifrom Hangzhou

Objective To optimize the best conditions of the cutting propagation techniques for medicinal Chrysanthemum morifolium from Hangzhou.Methods The effects of indole acetic acid(IAA),naphthalene acetic acid(NAA),and indole butyric acid(IBA) at concentration of 250,500,750,and 1 000 mg/L respectively on slips cutting of two different parts of medicinal C.morifolium from Hangzhou were studied.Results The rooting numbers of young shoots and stem segments were 13.63 and 5.96 respectively,indexes of root system were 3.13 and 1.4.Rooting of cutting wood treated with hormone was significantly better than that in the control group.The best rooting was obtained by treatment with 750 mg/L IBA with rooting index of 17.8.Conclusion This study provides a reference for the cutting propagation of medicinal C.morifolium from Hangzhou.
