[Objective] The study had developed a means of rapid propagation Pteris vittata L.by tissue culture. The species was a perennial fern belonging to the genus Pteris. [Metbed] The leaf bud of P. vittata collected in field conditions as explantsand the 1/2 MS ＋ 3% sucrose ＋ 0.7% agar as the basic medium were used to screen the medium formula of the phytohormone ratio for callus induction and subculture of P. vittata. [Result] The best medium formula for each step was list below： 1/2 MS ＋ 3% sucrose ＋ 0.7% agar ＋ 0.5 g/L PVP ＋ 0.1 mg/L KT ＋ 0.5 mg/L 2, 4-D for in- ducing the callus from explants; 1/2MS ＋ 3% sucrose ＋ 0.7% agar ＋ 0.5 g/L PVP ＋ 1.0 mg/L KT ＋ 0.01 mg/L 2,4-D for inducing the GGB from callus and the seedlings from GGB. In addition, 1/2 MS ＋ 3% sucrose ＋ 0.7% agar ＋ 0.5 g/L PVP ＋ 0.5 mg/L 2,4-D for the subculture could make the continued proliferation of callus. [Cen- clusioa] This study makes an applicable procedure by the direct use of field materi- als, for propagating P. vittata in a simplified and rapid mode.
