摘　　要：近年来,杨树速生丰产用材林发展势头强劲,但由于栽植面积大、树种单一、基因同质性等原因,致使病虫害发生,严重影响了出材率。本文对天津地区广泛栽植的黑杨派速生品种"中林杨"、深州杨和转双抗虫基因741杨(简称转基因741杨)的适生性进行了调查、比较,结果表明,转基因741杨在天津地区表现出较高的适生性,是天津地区较为理想的用材林杨树品种。Poplar tree is one of the primary breeds in the agricultural protection forests and fast-growing and high-yield forests. With the rapid development of forestry, the fast-growing and high-yield plantation got the strongest momentum. However, the large planting area, single species and genetic homogeneity led to pests and diseases which badly affected the out-turn percentage Based on the adaptability investigation and analysis of the fast-growing variety of Black Poplar, Zhonglin Poplar, extensively planted in Tianjin, Shenzhou Poplar and transgenic hybrid Poplar 741, the results show that the transgenic Poplar 741 is an ideal species of poplar timber, which showed high adaptability in Tianjin.
