摘　　要：以BH01、BH10、BH14等16个湖北省本地的泡桐无性系和C039、9501、9502等4个引进泡桐无性系为材料，用其截干带根苗造林，2005～2015年每年对试验林进行生长量和病虫害发生情况调查，并对10年生林木进行材性分析，筛选适合当地推广应用的泡桐无性系。结果表明：参试的20个泡桐无性系10年生单株材积存在极显著差异，BH14、ZH65的10年生单株材积极显著优于对照（9501）和其它无性系，其单株材积与对照相比其增益为22．03％、18．86％；同时具有材质优良、自然接干率高、抗性强等优点，适合在鄂中低丘岗地及类似地区栽培。The afforestation tests were carried out by using seedlings without stems, and the tested 20 Paulownia clones includes 16 ones native to Hubei province such as BH01, BH10 and BH14 and 4 alien clones such as C039, 9501, 9502, 1502. The growth and the incidence of pests and diseases of the experimental forest were investigated every year from 2005 to 2015, and analyses of wood properties of 10a trees were conducted in order to select elite clones of Paulownia which could be adapted to the local conditions. The results showed that there were significant difference among the tested 20 Paulownia 10a clones. The individual volumes of BH14 and ZH65 with 10-year-growth were higher than that of the control （9501） and other clones with increase of individual volume by 22.03% and 18. 86%, respectively. BH14 and ZH65 have excellent wood properties with high rates of natural stem extension and strong resistance, and they are suitable for plantations at low hilly land in central Hubei.
