摘　　要：为充分了解新引进的杜鹃花种质资源的特性、解决适宜本地区栽培品种少的问题,连续3年对新引进的28个杜鹃花品种的花期、花色、花瓣等主要花期特征指标及开花率、保存率等主要栽培适应性指标进行观察和分析。结果表明:各品种间主要花期特征及栽培适应性存在明显差异,28个杜鹃花品种按落叶与否、花色、花瓣及花期分类,并结合栽培适应性,筛选出‘五彩夏鹃’、‘劳动勋章’、‘天章’、‘辉煌’4个品种适合在杭州地区园林上推广应用。The purpose of this study was to have a good understanding of the characteristics of the introduced Rhododendron resources and to screen the appropriate variety for local cultivation. We compared 28 newly introduced Rhododendron cultivars, in which the main flowering characteristics and main cultivation adaptability index such as flower petals, blossom rate and survival rate were observed and analyzed for 3 consecutive years. The results showed that there were significant differences in flowering characteristics and main cultivation adaptability among the cuhivars. 28 Rhododendron cultivars were classified according to defoliation, flower color, flower petals, flower duration, as well as the cultivation adaptability. We finally selected four cuhivars including ＇Wucai Xiajuan＇, ＇Laodong Xunzhang＇, ＇Tian Zhang＇, ＇ Hui Huang＇, which were suitable for application in Hangzhou.
