摘　　要：蛇含委陵菜（Potentilla kleiniana）是一种生态适应性和观赏性兼具的乡土地被植物。本文在对蛇含委陵菜的形态特征和物候期进行观察记录的基础上,对其根系、匍匐茎和花序的生长特性进行了研究,以期为园林绿地的推广应用提供科学依据。结果表明：蛇含委陵菜花期为4-6月,全年无明显休眠期;地上匍匐茎和着生在其上的子株是重要的营养繁殖器官;主花序和子株分别集中分布在匍匐茎的第5节和第4-6节;根箱试验表明绝大部分根系集中分布在土深40cm左右。Potentilla kleiniana is an indigenous ground-cover plant with excellent ecological adaptability and ornamental value. On the basis of observation and records of the morphological characteristics and phenophase of Potentilla kleiniana, the growth characteristics of the roots, stolon and inflorescence were studied in this paper, which would be the scientific basis for promoting its landscape application. The results showed that： There was no obvious dormancy stage for Potentilla kleiniana with a florescence time from April to July; ground stolons and the sub-stolon were important vegetative reproduction organs; main inflorescence and sub-stolon mainly distributed in the fifth and the fourth to sixth nodes of stolon respectively; root case experiment showed that most roots distributed in the soil within a depth of 40cm.
