摘　　要：以白花泡桐全国37个种源对比试验林中筛选出的13个白花泡桐优良无性系为材料,并以9501、桐优1号以及江西种源白花泡桐平均株作为对照,建立赣北(共青城)、赣中(樟树)、赣南(赣州)3个区域的试验林,对13个无性系以及3个对照的树高、胸径进行测定和分析。结果表明:3个试验区各白花泡桐无性系生长量上均存在一定的差别,9号无性系在3个试验点均表现出较大生长优势;而23号在赣北和赣中区域表现最佳,25号则在赣南区域表现较好。The 13 clones of Paulownia fortune were selected from the 37 provenances of the P.fortune in China,and taking the 9501,Tongyou 1 and the average strain of P.fortune in Jiangxi Province as the control,to establish experimental forests in three regions of northern Jiangxi(Gongqingcheng),central Jiangxi(Zhangshu)and southern Jiangxi(Ganzhou).Measurement and analysis of tree height and DBH of 16 clones.The results showed that there were some differences in the growth of P.fortune clones in the three test areas.The No.9 clone showed great growth advantage at all three test sites.The No.23 was best performance in the areas of northern Jiangxi and central Jiangxi,and the No.25 was better in the southern Jiangxi.
