摘　　要：通过对扶芳藤野生资源及主要栽培种 (品种 )进行调查和收集 ,对其形态特征、生育期、年生长节律、繁殖习性、攀附特性、叶形、叶序及叶色季节性变化、花序及种子形态变异特征进行对比观察和研究 ,得出扶芳藤在我国分布范围广、种质资源丰富、种内变异类型多 ,且生长期长、易繁殖和适应性强等特点 ;并根据其主要特征将扶芳藤种质资源初步划分为 1 9个类型 。By investigating and collecting wild resources and main cultivated species of Euonymus fortunei , this paper introduced in detail its various morphological characteristics, period of duration, growth rhythm, breeding habits, climbing and creeping traits. The intraspecific variances in phylliform,phyllotaxy, leaf color, inflorescence morphology and seed shape were also observed and studied. The conclusions are as follows: there are many germplasm resources and variation types of Euonymus fortunei , which are widely distributed in China; they are easy to be propagated and have strong adaptability and long growth period. Efforts have been made to summarize the different variation forms into 19 types, which could serve as a basis for studies of selection, genetic improvement and further applications in broader areas.
