Abstract:: The effect of different phytohormones and concentration and treatment time on cutting propagation was analyzed using wild Thymus quinquecostatus in Changbai Mt.The results showed that the effect of plant growth regulators on average rooting rate was ABT>NAA>IBA，each was 94.22%,90.69%,81.33%.But the best rooting growth was NAA 1 000 mg/L(1 s) treatment.ABT solution was suggested when cutting wild Thymus quinquecostatus in Changbai Mt.area.Selecting ABT solution was little difference in treatment concentration，but the best was 500 mg/L(2 min).When we selected NAA solution there were differences among treatments，with the increase concentration，the effect was better，the best treatment was 1 000 mg/L(1 s).For IBA solution there were differences among treatments，with the increase of concentration，the rooting rate and rooting growth were worse，the best treatment was 50 mg/L(12 h).
