摘　　要：为促进鲜食葡萄品种的繁育及推广,以鲜食葡萄品种‘天工墨玉’为试材,探究了不同基质+不同浓度IBA对其硬枝扦插效果的影响。结果表明,采用珍珠岩为扦插基质,随着IBA浓度的升高,‘天工墨玉’硬枝扦插的生根率呈逐渐升高的趋势。在相同IBA浓度条件下,采用珍珠岩为扦插基质,‘天工墨玉’硬枝扦插的生根率最高;采用弹性基质为扦插基质,‘天工墨玉’硬枝扦插的生根率最低。采用珍珠岩和草炭土为扦插基质,IBA浓度为750和1000 mg·L^(-1)时,‘天工墨玉’硬枝扦插的根数在同一基质条件下无显著差异。综合考评‘天工墨玉’的叶片数量、根鲜重、根干重、叶片鲜重、叶片干重等指标,采用珍珠岩作为扦插基质,配以750 mg·L^(-1) IBA的效果较好。In order to promote the breeding and promotion of table grape varieties,in this study,the effects of different substrates+different concentrations of IBA on the cuttings of table grape‘Tiangongmoyu’were studied.The results showed that with the increase of IBA concentration,the rooting rate of‘Tiangongmoyu’hard branch cuttings gradually increases.Under the same IBA concentration,perlite was used as the cutting medium,and the rooting rate of‘Tiangongmoyu’was the highest.Using elastic medium as cutting medium,‘Tiangongmoyu’hard branch cutting had the lowest rooting rate.When the concentrations of IBA were 750 and 1000 mg·L^(-1) there was no significant difference in the number of hard cuttings of‘Tiangongmoyu’under the same medium condition.Leaf number,root fresh weight,root dry weight,leaf fresh weight,leaf dry weight and other indexes of‘Tiangongmoyu’were evaluated comprehensively,the perlite was used as cutting medium and 750 mg·L^(-1) IBA was used as hormone.
