三倍体毛白杨试管苗瓶外扦插繁殖的研究

Study on cutting propagation of the triploid Populus tomentosa using test-tube plantlets outside container

研究了不同浓度NAA处理对三倍体毛白杨试管苗切段扦插繁殖的影响.结果表明:50mg·L-1NAA处理的三倍体毛白杨试管苗切段生根早,根数多,茎叶生长健壮,成活率可达94%以上,比容器内繁殖省时省工,节约成本.

A study was conducted on the effect of different concentration of NAA treatments on the cutting propagation of triploid Populus tomentosa testtube plantlet cuttings. The main result shows that the cuttings which are treated by 50mg·L-1 NAA grow robustly,root early and yield more roots. The survival rate of cuttings can be over 94%. It saves not only time and labor, but also expense in comparison with propagation in the container.
