Gemplasm and Utilization Evaluation for Wild Plant Resources of Rosaceae in Qinghai Province

青海省野生蔷薇科植物资源丰富,共有26属102种22变种1变型,分析了植物区系特点,对观赏价值较高的21属68种2变种1变型的生境和观赏特性进行了分析,并对野生植物资源的园林应用进行了评价。结果表明:温带成分占绝对优势,占总属数的80.8%。观赏价值较高的植物中,木本植物有17属62种1变种1变型;叶形多样;花色丰富,以白色、红色和黄色系为主,其中以白色系居多;有单花和各种花序类型;果实有蓇葖果、梨果、核果和瘦果;果色有红色、白色、黑色、黄色。

There are abundant wild plants of Rosaceae including 102 species 22variants and 1form of 26 genera in Qinghai Province.In this paper,floristic characteristics were analyzed,and the habitat and ornamental characteristics of 68species2 variant 1form of 21 genera with high ornamental value were evaluated.The results showed that the geographic element of the flora was dominated by temperate element（80.8%）.62 species and 1variety and 1form（within 17genera）of woody plants had higher ornamental value.The results also showed that the leaf shapes of these plants were diversity,color of flower was predominant with white,red and yellow,and with white the most often ones.In terms of inflorescence types,there were solitary flowers and many inflorescence types.In terms of fruit types,there were follicle,pome,drupe ellipsoid and achene,and the fruit color had red,white,black,and yellow.Based on these information,and evaluated the landscape application of the main plant resources of Rosaceae in Qinghai Province.
