摘　　要：[目的]研究不同的生长调节剂对黑果枸杞硬枝扦插育苗的影响。[方法]采用5种不同生长调节剂75mg/LIBA、750mg/LIAA、750mg/LGGR7号、300mg/LNAA和300mg/LGA3对黑果枸杞插条进行处理,调查硬枝扦插的出苗率、新生枝数量、新生根数量、新生根平均根长。[结果]对黑果枸杞出苗影响最大的是IBA,其苗率最高为85%,其次是IAA(80%)、GGR7号(78%)、NAA(75%)、GA3(73%),清水出苗率最低为65%。NAA和GGR7号对黑果枸杞新生枝数量有显著促进作用。对黑果枸杞扦插苗新生根数量有极显著促进作用的是GGR7号,其次为IBA。对黑果枸杞扦插苗新生根平均根长有极显著促进作用的为GGR7号,其次为IAA。[结论]750mg/L生根粉GGR7号对黑果枸杞硬枝扦插育苗促进作用最大。[Objective]To study the effect of different growth regulator on raising seedlings of Lycium ruthenicum Murr by hardwood cuttings.[Method]5 kinds of different growth regulator including 75 mg/L IBA,750 mg/L IAA,750 mg/L GGR7,300 mg/L NAA and 300 mg/L GA3 were adopted in the treatment of cuttings of Lycium ruthenicum Murr.Then,emergence rate,new-shoot number and average new-root length of hardwood cuttings were respectively investigated.[Result]The emergence rate of Lycium ruthenicum Murr was influenced mostly by IBA at 85%,followed by IAA（80%）,GGR7（78%）,NAA（75%） and GA3（73%）,and the least by clean water at 65%.NAA and GGR7 could enhance the new-shoot number obviously.The new-root number was enhanced very significantly by GGR7,followed by IBA.The average new-root length was enhanced very significantly by GGR7,followed by IAA.[Conclusion]750 mg/L GGR7 could mostly promote the raising seedlings of Lycium ruthenicum Murr by hardwood cuttings.
