摘　　要：[目的]探究洋桔梗在东北地区穗条冬季扦插繁殖的可行性。[方法]以秋季成熟洋桔梗嫩枝作插条,于东北不加温温室内进行不同扦插部位(上部、中部、基部)的扦插育苗试验。[结果]在不加温温室内洋桔梗插穗能生根成活并越冬,上部插穗成活率和生根率均最高,分别达到89.91%和79.26%。[结论]该方法可在来年春季早期生产中推广使用。[Objective]The aim was to explore the feasibility of winter stem cutting propagation of Eustoma grandiflorum in the Northeast region.[Method]Using autumn mature young branches of E.grandiflorum as cuttings,experiments were conducted on different cutting parts(upper,middle,and base)in a warm room in Northeast China.[Result]The results showed that E.grandiflorus could survive the winter,the survival rate of upper cuttings and the rooting rate were the highest.[Conclusion]The utility model could be popularized and used in the production.
