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