摘　　要：为探究不同种类、浓度的GGR对紫叶风箱果硬枝扦插的影响,用4种类型的GGR设置不同浓度(50~350 mg·L-1)处理插穗后进行扦插试验。结果表明:4种GGR处理在50~350 mg·L-1时对风箱果插穗生根均有一定的促进作用,以150 mg·L-1的效果最好,存活率达92.66%。GGR-10在促进插穗生根及根系生长方面效果最好;GGR-6和GGR-7一般;GGR-8的效果较差。In order to explore the influence of different types and concentrations of GGR on hard-wood cuttings of Physocarpus opulifolius ’Di-abolo’, cuttings were conducted after four types of GGR were treated with different concentrations(50-350 mg·L-1), and rooting conditions were observed.Result shows that all four GGR treatments can promote the rooting of Physocarpus opulifolius ’Di-abolo’ cuttings at 50-350 mg·L-1, but 150 mg·L-1 have the optimal effect.GGR-10 have the optimal effect in promoting root rooting & root growth, GGR-6 and GGR-7 are average, while GGR-8 has a poor effect.
