摘　　要：为了提高黄金香柳嫩枝扦插生根率和扦插生根效果,筛选适宜的生根剂处理浓度。分别用400、600、800、1000 mg/L NAA处理插穗8 s,以CK清水为对照,研究不同浓度NAA处理对黄金香柳嫩枝扦插效果的影响。结果表明,随着NAA浓度的增加,生根率、根长、株高及新枝数呈现先上升后下降的趋势,根数和根径随NAA浓度增加不断上升,综合隶属函数评价结果,800 mg/L浓度下扦插效果最好。In order to improve the rooting rate and the effect of cutting rooting,the suitable concentration of rooting agent was selected.The cuttings were treated with 400,600,800 and 1000 mg/L NAA respectively for 8 s,and CK(clear water)was used as the control to study the effect of NAA treatment with different concentrations on the cuttage of Melaleuca bracteata.With the increase of NAA concentration,the rooting rate,root length,plant height and number of new branches increased first and then decreased.The number of roots and root diameter increased with the increase of NAA concentration.The cutting effect was the best at the concentration of 800 mg/L.
