Murashige and Skoog’s (MS) medium supplemented with 3 mg/L BA was the optimal medium for bud multiplication. The highest proliferation coefficient was 3.77, and the cluster buds grown well. The suitable rooting medium was 1/2 MS supplemented with 3 mg/L IBA. The rooting rate was up to 100%, and the roots were long and thick. The survival rate of hardening plantlets was 98% after being transferred to a mixture of peat, vermiculite and perlite with a ratio at 1:1:1. The study provides technical support for the propagation and industrialization production of Fargesia fungosa, and also is of important reference value to the tissue culture of other species in the genus.
