对三倍体毛白杨引种试验结果表明：三倍体毛白杨插穗（经过芽接、枝接后的小美旱、大官杨插条）的成苗率与嫁接方式、砧木种类相关性不显著；三倍体毛白杨苗期生长量与对照（普通毛白杨）相比差异显著，９０％以上可当年育成一级壮苗；造林后三倍体毛白杨幼树初期生长显著快于二倍体毛白杨。
The results of introduction experiments on Triploid Populus tomentosa showed that there was no significant correlation between the rate of seedling emergence and the grafting method and rootstock species of triploid Populus tomentosa cuttings (after the sprouting and grafting, Compared with the control (Populus tomentosa), the growth of A. solani seedlings at the seedling stage was significantly different. More than 90% of the A. sojae could grow into one strong seedling in that year. The initial growth of the triploid Populus tomentosa seedlings was significantly faster than that of the diploid Populus tomentosa.
