[Objective] The aim was to discuss the effects of plant growing regulators on the rooting of shoots of Trachelospermum jasminoides by soft-cuttings, so as to provide basic data for the species introduction and breeding of Trachelospermum jasminoides as well as the practical technique improvement of plant growth regulators.[Method] Speeding adhesional wetting method was adopted to study the effects of different concentrations of plants growing regulator (NAA and ABT-Rootone) on the rooting of shoots of Trachelospermum jasminoides by soft-cuttings.[Results] Results showed that the suitable concentration of auxin could significantly increase the rooting rate and quality with 200 mg/kg NAA for 5 minutes which could help to develop roots, and the rooting rate could reach to 58.82 %.[Conclusion] The shoots basis treated with 200 mg/kg NAA for 5 minutes was the effective way for the rooting of Trachelospermum jasminoide.
