摘　　要：为探讨盆栽条件下不同蜡梅(Chimonanthus praecox)品种的光合特性,为蜡梅盆栽(景)栽培管理提供参考,以2个不同花色、叶形的蜡梅品种‘鄢陵素心’(C.praecox’Yanlingsuxin’)和‘鸿运’(C.praecox’Hongyun’)4年生盆栽苗为试验材料,在4—11月对其光响应及叶绿素荧光参数进行测定。结果表明,2个蜡梅品种的光响应曲线和叶绿素荧光参数均无明显差异;初始量子效率(α)、最大净光合速率(P_(nmax))、光补偿点(LCP)等数据表明,2个蜡梅品种均有一定的耐荫性,较适宜盆栽。In order to explore photosynthetic characteristics of different Chimonanthus praecox cultivars under potted conditions,and provide reference for pot planting and management of C.praecox,4-year-old potted seedlings of C.praecox'Yanlingsuxin'and C.praecox'Hongyun'with different flower colors and leaf shapes were used as experimental materials.Light response and chlorophyll fluorescence parameters were measured from April to November.Results showed that there were no significant differences among light response curves and chlorophyll fluorescence parameters between two cultivars.Initial quantum efficiency(α),the maximum photosynthetic rates(P_(nmax))and light compensation points(LCP)showed that both cultivars had certain shade tol⁃erance and were suitable for pot planting.
