不同溶液浸泡处理对鹅掌柴扦插繁殖的影响

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。

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

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).
