摘要	Oreocharis mileense (W.T. Wang) M. Moller & A. Weber is endemic to China and was considered to be extinct because it had not been seen in the wild since the first collection in 1906. In 2006, the species was rediscovered in Shilin County, Yunnan Province. Oreocharis mileense was considered critically endangered for its narrow geographic range and extremely small population. An efficient method to preserve plant germplasm by in vitro culturing of O. mileense has not been reported. In this study, an orthogonal array with three factors (6-benzyladenine, BA; alpha-naphthaleneacetic acid, NAA; and sucrose), at four levels was performed, and shoot induction as well as shoot proliferation were recorded. The results were analyzed to determine the most significant components and the optimum combination for micropropagation of O. mileense. The results showed that: (1) organogenesis was easily induced by different combinations of plant-growth regulators and sucrose; (2) NAA and sucrose had the most significant effect on shoot induction and shoot multiplication, and (3) the optimum induction and proliferation media were 0.5 mg L-1 BA + 0.2 mg L-1 NAA + 30 g L-1 sucrose and 1 mg L-1 BA + 0.1 mg L-1 NAA + 30 g L-1 sucrose, respectively.
