摘　　要：[目的]对连翘花及其变异类型的形态学进行研究。[方法]采用形态学观察法对连翘的2种正常花型和新发现的7种变异花型进行形态特征观察,并在此基础上探讨连翘花的演化趋向问题。[结果]连翘为二型花柱植物,连翘花型的变异体现在花冠裂片和雄蕊数量的不同上。[结论]该文对连翘花及其变异类型的形态学进行了研究,为深入研究连翘花各部变异的发生机理提供依据。[ Objective ] To study morphology of Forsythia suspensa flower and its mutation type. [ Method] In morphological observation, the morphological characteristics of 2 kinds of normal and 7 kinds of newly discovered mutated F. suspensa flower were observed. On the basis of this, the evolution trend was discussed. [ Result ] The results showed that F. suspensa is distyly plant, the mutation of F. suspeusa flower is reflected in the different number of the corolla lobe and stamen. [ Conclusion ] The morphology of F. suspeusa flower and its mutation types were studied, which will provide the basis for further research on the mutation mechanism of F. suspensa flower.
