IBA·NAA对石蒜·换锦花鳞片扦插繁殖技术的研究

摘要

[目的]筛选石蒜扦插繁殖的激素配方和浓度,为石蒜冬季扦插生产提供基础资料.[方法]以IBA和NAA的4种不同的激素浓度组合成16种激素配方,对石蒜、换锦花鳞片扦插繁殖进行研究.[结果]不同浓度的NAA和IBA溶液对石蒜、换锦花的增殖系数、鳞茎均重和平均生根教有一定的影响,综合考虑,NAA和IBA混合溶液以浓度25～50 mg/L较为理想;石蒜在扦插过程中能够获得较高的增殖系数,而小鳞茎的均重较低.[结论]石蒜(L.radiata)和换锦花(L.sprengeri)冬季扦插生产是可行的.%[ Object] To select the optimum hormones ratio and concentration for the scale cutting propagation of Lycoris plants,so as to provide basis for the production of Lycoris plants in winter. [ Method ] 4 concentrations of IBA and NAA were combined randomly into 16 formulas. [ Result ] Different concentrations of IBA and NAA have a certain effect on the multiplication coefficient, bulb mean weight and average rooting number,and the concentration of NAA-IBA mixed solution was proved to be the best in the range of 25 ～ 50 mg/L; under this condition ,the multiplication coefficient of Lycoris plants was higher with lower bulb mean weight. [ Conclusion ] It is feasible to carry out scale cutting propagation of Lycoris radiate and Lycoris sprengeri in winter.
