摘　　要：［目的］研究彩叶植物的生长节律。［方法］对红叶石楠（Phtinia×fraseri‘Red Robin’）、小丑火棘（Pyrachtha fortuntana ‘Herleguin’）、水果蓝（Teucrium fruitcans）、金叶大花六道木（Abelia grandiflora‘Francis Mason’）及北美枫香（Liquidambar styraciflua）5个彩叶树种连续3年进行株高和冠幅测量。［结果］小丑火棘、金叶大花六道木、水果蓝3个品种的冠幅生长量大于株高的生长量，其余2个品种与之相反。另外，从不同月份的生长量来看，除北美枫香的生长高峰为7月外，其余4个品种的生长高峰都在4～5月。［结论］研究结果可以为彩叶树种的栽培管理和园林应用中的植物配置提供参考。[ Objective ] The rhythm of the color-leaf plant growth was studied. [ Method ] The plant height and crown width of 5 species of color-leaf plants ： Red Robin （ Phtinia x fraseri ） , Herleguin （ Pyrachtha fortuntana ） , Teucrium fruitcans , Francis Mason （ Abelia grandiflora ） and Liquidambar styraciflua were measured for successive 3 years. [ Results ] The results showed that the growth of the crown width of Herleguin, Francis Mason and Teucrium fruitcans was significantly larger than that of their plant heights; in contrast with the other two trees. In addition, from view the growth per month, in addition to the Liquidambar styraciflua, which growth peak was in July, the growth peak of other four species was in period from April to May. [ Conclusion] The results could be referred for the cultivation management of color-leaf plant and their application in landscape design.
