【摘要】 [目的]探讨西宁地区金叶风箱果(Physocarpus opulifolium Lutein)的优良苗木繁育方法。[方法]对金叶风箱果半木质化嫩枝采用吲哚丁酸(IBA)、荼乙酸(NAA)、ABT6号生根粉处理,然后进行扦插试验。[结果]扦插前用不同浓度IBA、NAA、ABT6号生根粉浸蘸插穗基部,生根效果不同。ABT6号生根粉处理各浓度平均成活率为23.22%,NAA各浓度处理平均成活率为14.61%,IAA处理各浓度平均成活率为10.72%,ABT6号生根粉处理与NAA、IAA处理存在显著差异。[结论]ABT6号生根粉与IBA、NAA相比有明显提高金叶风箱果插穗成活率的效果。更多还原

【Abstract】 [Objective] To discuss good seedling breeding methods of Physocarpus opulifolium Lutein in Xining Area.[Method] Physocarpus opulifolium Lutein’s semi-ligneous young branches treated with IBA,NAA,ABT6 rooting powder were chose to carry out cutting test.[Result] There were different rooting effects when cutting base were immersed in IBA,NAA and ABT6 rooting powder before cutting resp..Average rooting rate of ABT6 rooting powder,NAA and IBA treatments under all concentrations was 23.22%,14.61% and 10.72% resp.,and ABT6 rooting powder treatment had significant difference with NAA and IBA treatment.[Conclusion] Comparing to IBA and NAA,ABT6 rooting powder has significant effects of improving cutting survival rate of Physocarpus opulifolium Lutein.更多还原
