Ｑ育根素应用在毛白杨“炮捻”插穗中的接穗上的结果是：一是加速砧木、接穗间的愈合，并促进愈伤组织形成和进而分化出“次生根原基”以及由它生育成“自生根”根系。从而提高了“炮捻”插穗扦插成活率和赢得了“地上”、“地下”两部分的生长发育时空一加长“生育期”。二是经处理的“炮捻”插穗的苗高、地径、根量、成苗率和生物量５项经济指标均比对照高出５０％左右，故其纯收益提高４．７倍。总之，Ｑ育根素应用在毛白杨“炮捻”插穗育苗上是成功的。
The results of applying Q. yungenin to the scion in Populus tomentosa cuttings are: accelerating the healing between rootstock and scion, and promoting callus formation and differentiation into “secondary root primordia” Fertility as “rooting” roots. Thus increasing the survival rate of Cuttage twisting cuttings and winning the “growth period” of growth and development in two parts of “above ground” and “underground”. Second, the processed “gun twist” cuttings of seedling height, diameter, root volume, seedling rate and biomass of five economic indicators were higher than the control of about 50%, so the net income increased by 4.7 times. In short, Q Yu-gen application of Populus tomentosa “shoot twist” cutting seedling is successful.
