摘　　要：为了挽救、保护和综合利用珍贵的泡桐Paulownia种质资源,对全国20个省(直辖市)进行泡桐种质资源调查收集,并对其保存和繁殖技术进行了研究。到2009年底,共搜集到338份泡桐种质资源,其中包括50个生长量大、干形好、抗性强的白花泡桐Paulownia fortune优良单株资源;在河南温县、湖北赤壁和江西九江共营建21.73hm3泡桐基因库,对搜集的资源进行保存;进行了嫁接,扦插,组织培养和埋根等幼化繁殖试验,成功地探索出了白花泡桐老龄优树的幼化繁殖技术。In order to save,protect and utilize comprehensively the germplasm resources of Paulownia,the investigation and collection of the germplasm resources of Paulownia in 20 provinces（municipalities） of China were conducted,and the conservation and propagation techniques were studied.The results are as follows：by the end of the year 2009,there were 388 of Paulownia germplasm resources to be collected,including 50 Paulownia fortunei superior trees germplasm resources which grew faster and had stronger resistance and good trunk form;Paulownia gene banks total area of 27.73 hm2 were built in Wenxian of Henan and Chibi of Hubei and Jiujiang of Jiangxi provinces.And the collected germplasm resources was conserved;and the experiments of grafting,cutting,tissue culture and burning root were carried,then the rejuvenation and propagation techniques of the old Paulownia fortunei superior tree material were successfully developed.
