金边瑞香水培扦插繁殖试验技术研究

Study on Experimental Technology of Hydroponic Culture Cutting Propagation of Daphne odora var. marginata Mak

以金边瑞香为试验材料,采用正交试验方法,研究了不同浓度IAA、IBA、NAA及扦插基质花泥、海绵、珍珠岩对金边瑞香水培扦插成活及生根的影响。结果表明,生根剂种类、生根剂浓度及扦插基质对金边瑞香扦插成活及根长有显著影响,对生根数量影响差异不显著。生根剂采用IBA处理平均成活率达80.00%,1000 mg/L的生根剂处理平均成活率达80.55%,花泥扦插处理平均成活率达89.33%。6号组合IBA+1000 mg/L+花泥扦插成活率为94.00%,明显高于其他组合(P<0.05),达到了提高扦插成活率的目的,值得应用推广。

Using the orthogonal experimental design method,the effects of different concentrations of IAA,IBA,NAA,as well as cutting medium such as floral foam,sponge and perlite on the cutting survival and rooting of Daphne odora var.marginata Mak were studied.The results showed that:the type of rooting agent,the concentration of rooting agent and the cutting substrate had significant effects on the survival and root length of Daphne odora,but there was no significant difference in the number of roots.The average survival rate of rooting agent treated with IBA was 80.00%,the average survival rate of rooting agent treatment with a concentration of 1000 mg/L was 80.55%,and the average survival rate of floral foam cutting treatment was 89.33%.The survival rate of No.6 combination IBA+1000 mg/L+floral foam cuttings was 94.00%,which was significantly higher than other combinations(P<0.05).It achieved the purpose of improving the cutting survival rate and was worthy of application and promotion.
