短柄五加嫩枝扦插育苗技术研究

Study on Young Branch Cutting Seedling Technique of Eleutherococcus brachypus

[目的]短柄五加有性繁殖育苗相对较为困难,为解决种苗来源问题,积极探索短柄五加无性繁育种苗的方法。[方法]使用植物生长调节剂ABT 1生根粉与吲哚丁酸钾(IBAK)原粉对短柄五加年幼枝条进行处理,考察不同浓度生根粉溶液与不同扦插时间扦插繁育的成苗情况。[结果]短柄五加嫩枝扦插的最佳时间应在每年的7月1-15日,ABT_(1)生根粉溶液与吲哚丁酸钾原粉溶液对短柄五加年幼枝条成苗率分别较对照处理提高了23.62%和21.89%,达到80%以上。[结论]该研究对短柄五加无性繁殖育苗具有一定的技术指导意义。

[Objective]The sexual propagation of Eleutherococcus brachypus was relatively difficult.In order to solve the source of seedlings,the method of asexual propagation of Eleutherococcus brachypus was actively explored.[Method]The young branches of Eleutherococcus brachypus were treated with plant growth regulator ABT1 rooting powder and potassium indolebutyrate rooting powder,and the cutting propagation of Eleutherococcus brachypus with different concentrations of rooting powder solution and different cutting time was investigated.[Result]The best time for young branch cutting of Eleutherococcus brachypus was between July 1 and 15 of the year.The seedling percentage of Eleutherococcus brachypus treated with ABT_(1) rooting powder and potassium indolebutyrate solution increased by 23.62%and 21.89%,respectively,reaching over 80%.[Conclusion]This study has certain technical guidance significance for asexual propagation of Eleutherococcus brachypus.
