摘　　要：为做好川西南二半山区杨树无性系初步选育工作,进一步满足当地造林需求,加快杨树产业发展,分别引进28个杨树无性系,选取布拖县开展苗期试验;以地径和苗高两个主要苗期生长量为指标,初步筛选出适宜在该区域生长的优良无性系。采用方差分析和多重比较分析等方法,结果表明1年生各杨树无性系间苗期生长性状差异较大,以地径和苗高两因素为依据,南林312苗期表现最优,从而为杨树优良无性系在川西南二半山区的推广应用提供参考。In order to select excellent poplar clones in the mid-altitude mountain area in Southwest Sichuan, further meeting the needs of local afforestation and speeding up the development of poplar industry, 28 poplar clones were introduced respectively, and Butuo county was selected to carry out the seedling test. Using ground diameter and seedling height as indexes, excellent clones suitable for growing in this area were preliminarily selected. By using the methods of variance analysis and multiple comparison analysis, the results showed that there were great differences in seedling growth traits among 1-year-old poplar clones, and Nanlin 312 was the best at seedling stage according to ground diameter and seedling height, which provided a reference for the popularization and application of excellent poplar clones in the mid-altitude mountain area s in Southwest Sichuan.
