Abstract:In order to realize the status and ornamental value of wild germplasm resource of Rhodoleia (Hamamelidaceae) in China, a detailed field survey and recourse collection of 6 species of Rhodoleia was conducted. Based on cultivation experiments, a comprehensive evaluation index system was established by linear weighted synthesis method, and the potential in landscape application of Rhodoleia species were evaluated. The result showed that the comprehensive value of R. championii, R. stenopetala, R. parvipetala was high (Grade I with score>2.0), that of R. henryi was medium (Grade II with score 1.5-2.0), and that of R. forrestii and R. macrocarpa was low (Grade III with score<1.5). As excellent local arbors with gorgeous flower, R. championii, R. stenopetala, and R. parvipetala bear very high application potential in ornamental value, cultivation adaptability and novelty of development, which is worth further investigation and utilization.
