【摘要】 以金叶接骨木（Sambucus canadensis‘Aurea’）和胶东卫矛（Euonymus kiautshovicus）为材料,研究了不同浓度(50、100mg·L^-1)和处理时间（30、60min）的吲哚乙酸（IAA）、吲哚丁酸（IBA）、萘乙酸（NAA）对金叶接骨木和胶东卫矛扦插生根的影响。结果表明:IAA、IBA、NAA三种生长素均能促进扦插生根,但促进效果各不相同。100mg·L^-1的NAA处理60min能显著促进金叶接骨木生根,在生根率和生根数方面都明显高于对照;胶东卫矛经50mg·L^-1IBA处理30min后,生根率、生根数和平均根长都显著增加;虽然IAA处理能显著提高金叶接骨木的生根数和胶东卫矛的生根率,但没有NAA和IBA处理的效果好。另外,生长素的浓度水平以及处理时间都对金叶接骨木和胶东卫矛插穗的生根效果影响显著。更多还原

【Abstract】 Sambucus canadensis ’ Aurea’ and Euonymus kiautshovicus were used to research the effects of different auxin（IAA,IBA and NAA） concentrations(50、100mg · L^-1) and processing times（30、60 min） on cutting rooting.The results showed that three kinds of auxin（IAA,IBA and NAA） all significantly improved cutting rooting,but promoting effect each were not identical.Compared with the control,the rooting percentage and root number of Sambucus canadensis ’ Aurea’ were improved remarkably with 100 mg · L^-1 NAA treatment for 60 min.As to Euonymus kiautshovicus,50 mg · L^-1 IBA treatment for30 min significantly increased rooting percentage,root number and root length.Although IAA treatment could improve markedly the root number of Sambucus canadensis ’ Aurea’ and rooting percentage of Euonymus kiautshovicus,the promoting effect was not good compared with IBA and NAA.In addition,different auxin concentrations and processing times brought the striking difference on cutting rooting.更多还原
