不同溶液浸泡处理对鹅掌柴扦插繁殖的影响

Effects of Different Dipping Solution on the Cuttings of Schefflera octophylla in Cutting Reproduction Study

  • 摘要: 以清水对照,用多菌灵+福美双溶液和NAA+IBA溶液对鹅掌柴插穗浸泡处理后扦插,试验对插穗的形态生长指标和生根过程进行了统计,并对插穗内源性激素IAA、ABA的含量进行了分析。结果表明:NAA+IBA和适宜的多菌灵+福美双溶液均可提高插穗的生根率,促进根生长。经浸泡处理的插穗的成活率显著地高于对照(p<0.01)。多菌灵+福美双溶液浸泡插穗3h的理论最佳浓度为519mg/L。519mg/L多菌灵+福美双和200mg/LNAA+IBA处理都提高了插穗IAA的含量,ABA的含量却有所降低。用519mg/L多菌灵+福美双和200mg/LNAA+IBA分别浸泡插穗1.5h,成活率达到95.6%,比单独用200mg/LNAA+IBA处理的成活率提高了10%(p<0.05);实验结果还表明,鹅掌柴的生根属混合生根型。

     

    Abstract: The cuttings of Schefflera octophylla were dipped in two solutions and water control for cutting reproduction experiments.The two solutions contain Carbendazim+Thiram and NAA+IBA,respectively.Form growth index and endogenous hormone dynamics,IAA and ABA,during whole rooting process,were studied.The results indicated that NAA+IBA and Carbendazim+Thiram can promote rooting.The survival rates of the cuttings dipped in solutions were more significant than the control group(p<0.01).The best concentration of Carbendazim+Thiram was 519 mg/L dipped for 3 h.The treatments of 519 mg/L Carbendazim+Thiram and 200 mg/L NAA+IBA enhanced the content of IAA in basal stems,while reduced ABA.After treated for 1.5 h with the mixture of the two solutions,the survival rate reaches 95.6%,increased 10% than only treated by 200 mg/L NAA+IBA(p<0.05).The results showed that cutting of S.octophylla were mix-striking root(adventitious roots originated from cortices and calli).
