Effect of Different Growth Regulator on Raising Seedlings of Lycium ruthenicum Murr by Hardwood Cuttings

[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,new-root 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.
