The results showed that the seed germination rate of J. mimosaefolia reached up to 55.6% after warm water immersion for 60 minutes at 40℃-45℃. The optimum mediums for induction of adventitious buds and callus were MS+6-BA 2.0 mg L-1+NAA 0.1 mg L-1+2,4-D 0.1 mg L-1, and MS+6-BA 0.5 mg L-1+NAA 1.0 mg L-1+2,4-D 1.0 mg L-1, respectively. The optimum mediums for proliferation of adventitious buds and callus were modified MS+6-BA 0.5 mg L-1+NAA 0.5 mg L-1+IBA 0.5 mg L-1, and MS+6-BA 1.0 mg L-1+ NAA 0.5 mg L-1+ZT 3.0 mg L-1, respectively. The optimum medium for callus differentiation was MS+6-BA 1.0 mg L-1+NAA 0.5 mg L-1+2,4-D 0.5 mg L-1. The optimum rooting medium was 1/2MS supplemented with 20 g L-1 sugar and NAA 0.5 mg L-1 and 2.0 g L-1 active carbon (AC) with rooting up to 78.3%.
