摘　　要：为丰富成都地区彩叶树种资源,于2009年12月在成都崇州羊马引种美国红枫、北美枫香、北美海棠、紫叶矮樱、紫叶加拿大紫荆5个彩叶树种,对其成活率、生长势、生长量、物候、观赏性状和病虫害发生情况等进行了观察分析。结果表明,5种彩叶树种的引种成活率为80%～100%,地径年均生长量为0.4～0.9 cm,树高年均生长量为32～83 cm,冠幅年均生长量为15～76 cm,最佳色叶观赏期为49～150天,色叶期为90～282天和有叶期为258～303天,病虫害发生率为9%～95%。其中美国红枫、北美枫香、北美海棠和紫叶加拿大紫荆4个彩叶树种在崇州羊马综合生长表现较好,适应性较强,可作为适宜栽培的彩叶树种;紫叶矮樱生长速度最慢,病虫害发生率最高,达95%,不适宜在崇州羊马引种栽培。To enrich the species resources of colored-leaf trees in Chengdu region, 5 colored-leaf tree species, Acer rubrum, Liquidambar styraciflua, Malus ＇ Royalty＇ , Prunus × cistena, Cercis canadensis ＇ ForestPansy＇ , were in- troduced to Yangma of Chongzhou in 2009. The survival rate, growth potential and increment, phenophase, ornamen- tal characteristics, disease and pests were studied. The results showed that the survival rate of five species was 80 % ~ 100 %, average annual growths of ground diameter , tree height and crown width were 0. 4 ~ 0. 9 cm, 32 ~ 83 cm and 15 ~76 cm respectively, the best ornamental periods of colorful leaves were 49 -150 days, the periods with col- orful leaves and with leaves were 90 - 282 and 258 - 303 days respectively, the rate of diseases and pests was 9 % 95 %. Among of them, four trees species, A. rubrum, L. styraciflua, M. spectabilis and C. Canadensis ＇ ForestPan- sy＇ , performed well and were suitable to be planted in Yangma town of Chongzhou.
