摘　　要：为探究不同浓度生长调节剂对‘低糖枸杞’嫩枝扦插的影响,本试验以红果‘低糖枸杞’枝条为试材,通过测定嫩枝扦插成活率及其新梢生长量、根系生长量、生根数、平均生芽数等指标,研究不同浓度NAA、IBA、NAA+IBA、ABT(9个处理)对嫩枝扦插及其幼苗生长的影响。结果表明,外施适宜浓度的生长调节剂可提高枸杞扦插成活率,增加枝条的新梢生长量和扦插枝条的生根数,并促进枝条旺盛生长。利用主成分分析法对各处理效果进行综合排名,由大到小为T2(100 mg/L NAA)>T3(250 mg/L NAA)>T7[250 mg/L(NAA+IBA)]>T6[100 mg/L(NAA+IBA)]>T5(250 mg/L IBA)>T1(清水)>T8(100 mg/L ABT)>T4(100 mg/L IBA)>T9(250 mg/L ABT)。其中,T2处理整体效果最好,不仅可以促进萌芽及新枝生长,还可促进扦插苗生根,即扦插苗生根率高、生根数量多、根系长粗,可在生产实践中推广应用。To investigate the effects of different concentrations of growth regulators on cutting effect and shoot growth of red fruit wolfberry(Matrimony vine),tender branches of ‘low sugar goji berry' were used as test materials,9 treatments with different concentrations of NAA,IBA,NAA+IBA and ABT were set,and the survival rate of tender branch cuttings and the new shoot growth,root growth,root number,average number of sprouts and other indicators were measured.The results showed that appropriate concentrations of exogenous growth regulators could improve the survival rate of cuttings and the growth of new shoots,increase the number of roots in the cuttings,and promote vigorous growth of the branches in wolfberry.Comprehensive rank of the treatment effects obtained by principal component analysis was as T2(100 mg/L NAA)>T3(250 mg/L NAA)>T7 [250 mg/L(NAA+IBA)]>T6 [100 mg/L(NAA+IBA)]>T5(250 mg/L IBA)>T1(clear water)>T8(100 mg/L ABT)>T4(100 mg/L IBA)>T9(250 mg/L ABT).Among all the treatments,T2 performed the best,which could not only promote sprouting and new branch growth,but also enhance rooting of cutting seedlings with higher rooting rate and larger number and thicker roots,so it was worth promoting and applying in production practice.
