摘　　要：为了建立银杏‘渝成1号’硬枝扦插繁殖技术,本文研究了不同生根液和扦插基质对银杏‘渝成1号’扦插生根成苗的影响。结果表明:在3~6月份,以一年生枝条为插穗,用300 mg/L生根粉(ABT-1)配制的溶液处理插穗5 h后,插穗在营养土基质中的愈伤组织形成率、生根率、成活率分别是85%、72%和72%,这3个指标均高于其余三类基质的同类指标。据此认为,1年生枝条 + 300 mg/L ABT+ 5 h + 营养土的组合处理适用于银杏‘渝成1号’扦插苗的繁殖。To establish an effective propagation technology of hardwood branch cuttings of Ginkgo biloba ‘Chengyu No.1’, effects of different solutions and cutting substrates on rooting and seedling establishment were investigated in this study. The results showed that the cuttings from one-year-old branches were feasible after they were treated by 300 mg/L ABT-1 for 5 hours, and the callus formation rate, rooting rate, and survival rate of these cuttings in the substrate of nutrient soil were 85%, 72%, and 72%, respectively. These three indicators were higher than those of the other three types of cutting substrates. Thus, it was concluded that the combination of one-year-old cutting + 300 mg/L ABT-1 + 5 h + nutrient soil could be suitable for cutting propagation of G. biloba ‘Yucheng No.1’.
