摘　　要：为了丰富湖南的观赏桃品种,以引进的20个同年龄不同株型观赏桃品种为研究对象,在立地条件基本相同的大田条件下,对其生长指标及光合参数进行了测定。根据其流胶病抗病性进行聚类,并对其生长指标进行了综合评价。结果表明,根据生长势强弱,绛桃、满天红为一类,综合评判值在0.6以上,综合生长能力最强;生长势较强的有合欢二色、鸳鸯垂枝、绯桃、元春、粉花山碧、照手白、朱粉垂枝、照手桃、菊花桃、黛玉垂枝、粉红山碧;生长势中等的有寿白、洒红龙柱、寿红、二乔;生长势弱的有寿粉、照手姬、洒红。In order to rich cultivars of ornamental peach in Hunan, using 20 cultivar of ornamental peach with same age but different plant types as research objects, their growth indexes and photosynthetic parameters were determined under same site conditions. The cultivars were clustered based on the resistance to gummosis, and the growth indexes were evaluated comprehensively. The results showed that： based on the growth vigor, Jiangtao and Mantianhong were clustered into one group, and they showed the best growth performance and comprehensive evaluation values were more than 0.6. The cultivars with stronger growth vigor included Hehuan＇ erse, Yuanyangchuizhi, Feitao, Yuanchun, Fenhuashanbitao, Teruteshiro, Zhufenchuizhi, Terntemomo, Jutao, Daiyuchuizhi, and Fenhongshanbitao. The ones with middle growth vigor included Shoubai, Sahonglongzhu, Shouhong, and Erqiao. The ones with weak growth vigor included Shoufen,Terutehime, and Sahong.
