摘 要:北美鹅掌楸为重要的园林绿化树种,但北方地区相关研究较少,为丰富北方地区园林绿化树种的多样性,提高城市绿化质量,现对引种的宾夕法尼亚州种源和俄亥俄州种源的北美鹅掌楸实生苗地径、树高生长量变异及其分枝情况进行了初步分析。结果表明:宾夕法尼亚州种源北美鹅掌楸苗木在山东区域内的综合表现较俄亥俄州种源北美鹅掌楸苗木好,是山东区域内乃至周边区域引种和着重发展的重要种源,但其实生苗木侧分枝数量较多,在培育初期需要进行人工抹芽等抚育措施。Liriodendron tulipiferi, ra is an important landscaping tree species,but less research has been carried out in northern of China. In order to rich tree species diversity of northern China and improve the quality of urban greening,the variance of the diameter at butt-end and tree height and the number of branches between the two provences of Liriodendron tulipifera which were introduced emphatically were analyzed. The result indicated that: The Pennsylvanian provence of L. tulipifera introduced specially was more adaptive for Shandong area,even for around the region of Shandong than the Ohio provence of L. tulipifera. It was the important provence for Shandong area and around region to introduce and cultivate. But it has more branches than the trees of Ohio provence of L. tulipifera and ,some more manual cultivation should be done in the early stage.
