三倍体山杨具有生长快、体态大、生产性能高等特点,是一种很有发展前途的杨树引进品种。三倍体山杨能否在我国大量繁殖,并应用于大面积造林,关键在于它的无性繁殖能力。众所周知,杨属以白杨派无性繁殖难度较大,迄今,毛白杨(P.tomentosa)、银白杨(P·alba)、河北杨(P·nopeiensis)等品种虽已通过根繁或嫩枝扦插手段,基本解决了无性繁殖问题,但作为白杨组中无性繁殖难度较大的山杨,其无性繁殖间题仍为林业工作者所关注,
Triploid poplar has the characteristics of fast growing, big body and high production performance, which is a very promising poplar introduced species. Triploid Populus can multiply in our country, and applied to large-scale afforestation, the key lies in its asexual reproduction. As we all know, Populus poplar to cling to asexual reproduction is more difficult, so far, Populus (P.tomentosa), Populus (P · alba), Hebei poplar (P · nopeiensis) and other varieties have been through the root or softwood cutting means , Basically solved the problem of asexual reproduction, but as Poplar Populus asexual reproduction more difficult poplar, the problem of asexual reproduction remains the concern of forestry workers,
