Effects of exogenous hormones on rooting of Euonymus hamiltonianus and E. alatus cuttings.

The research on the cutting propagation of Euonymus hamiltonianus and E.alatus was carried out using NAA,IAA and GGR-6 at 50,150,300 mg.L-1 concentrations in order to provide references to their rapid propagation in large volume.The results showed that(1) the rooting of E.hamiltonianus belonged to callus rooting type;The GGR-6 concentration of 300 mg.L-1 had marked the best effects for E.hamiltonianus taking such the factors into account as rooting percentage,the length and number of roots.(2) the rooting of E.alatus belonged to comprehensive rooting type which were bark and callus rooting;300 mg.L-1 IAA had the best effect on rooting percentage of E.alatus,which reached to 91.10%.
