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).
