Abstract: 【OBJECTIVE】Through the studies, find out suitable plant growth regulator and appropriate concentration for Euonymus japonicus Thunb rooting cuttings .【METHOD】Conduct rooting effect tests with different treatments of three plant growth regulators of different concentrations or different mixture on Euonymus japonicus Thunb.-year-branches, then analyze the rusults respectively.【RESULTS】(1)Treatment with IBA50mg/L possesses most significant rooting effect , followed by treatments with IAA50mg/L, treatment of NAA50mg/L had little effect .(2) Optimal treatment concentrations of IBA, IAA and NAA for Euonymus japonicus Thunb.rooting cuttings are 50mg/L. (3)The effect of mixed using of different plant growth regulators on Euonymus japonicus Thunb.was not obvious, the combined using of IAA50mg/L +NAA50mg/L and IBA50mg/L+NAA50mg/L were not recommended on production..【CONCLUSION】Of all the treatments in the tests, treatment with IBA50mg/L possesses best rooting effect on Euonymus japonicus Thunb.rooting cuttings; the combined usage of IAA50mg/L +NAA50mg/L and IBA50mg/L+NAA50mg/L were not recommended on production.
