摘　　要：通过试验表明:胡杨硬枝用100 ppm ABT1#浸泡6 h,生根率最高为73%;嫩枝用100 ppm ABT1#浸泡6 h,生根率最高为69%。硬枝扦插平均生根率达到59%,嫩枝扦插平均生根率为52.5%,表明硬枝扦插生根率要比嫩枝扦插生根率高。After soaking in 100 ppm ABT1# for six hours,the biggest rooting rate of hardwood and softwood of Populus diversifolia Schrenk can reach up to 73% and 69% separately.The average rooting rate of hardwood cutting is 59%,and the one of softwood cutting is 52.5%,which show the rooting rate of hardwood cutting is higher than the one of softwood cutting.
