Effects of Different Treatments on Rooting of Machilus pauhoi Cuttings

The experiment was conducted to study the effects of different concentrations of ABT1 and different spike deals and xanthation on rooting of Machilus pauhoi cuttings. The results showed that there were significant differents in the survival rate and rooting rate of M. pauhoi among different concentrations of ABT1, different spike deals and xanthation respectively(P0.05), but there were not significant difference with xanthation on rooting of M. pauhoi cuttings. With the treatment of 200 mg/L of ABT1, the survival rate and rooting rate of M. pauhoi were 53.0% and 39.8% respectively. The effects of M. pauhoi cutting a half leaf were much better than those of one leaf, meanwhile the survival rate and rooting rate were 47.8% and 35.2%, which increased by 7.9% and 5.4% respectively. The cuttings survival rate and rooting rate of xanthation were 56.3% and 43.5% respectively, which increased by 25% and 22.1% respectively while compared with those of not being treated with xanthation.
