摘　　要：为了探索科学高效的紫叶矮樱扦插育苗技术,选用ABT、NAA和IBA 3种生长激素,按不同浓度、浸泡时间对1年生插穗进行处理,利用扦插生根率、苗高、新生枝基径、根长、新生根基径、枝干重、根干重等指标对扦插效果进行评价。以生根率大于50.0%为基准指标,初选出11种激素处理方法,并进行方差分析、多重比较、聚类分析和隶属函数综合评价,通过对比分析,最终筛选出紫叶矮樱扦插育苗最佳激素处理方法为ABT-100 mg/L-2 h。In order to explore the scientific and efficient cuttage techniques for Prunus × cistena,one-year cuttings have been treated with ABT,NAA and IBA in different concentrations and soaking time,and the cuttage effects have been evaluated with rooting rate,seedling height,basal diameter of new branch,root length,basal diameter of new root,dry weight of branch and dry weight of root. Taking rooting rate more than 50% as the basic index,11 kinds of hormone treatment have been chosen,after variance analysis,multiple comparison,cluster analysis and subordinate function comprehensive evaluation,the best hormone treatment is ABT-100 mg/L-2 h for cuttage breeding of Prunus × cistena.
