摘　　要：[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.[目的]对凤尾蕨科植物蜈蚣草的组织培养方法进行研究。[方法]以野外采集的叶芽为外植体,以1/2MS+3%蔗糖+0.7%琼脂为基本培养基,通过激素配比试验,筛选蜈蚣草愈伤组织诱导和继代培养的培养基配方。[结果]从外植体诱导出愈伤组织最佳培养基配方为1/2MS+3%蔗糖+0.7%琼脂+0.5g/LPVP+0.1mg/LKT+0.5mg/L2,4-D;从愈伤组织诱导出GGB和从GGB诱导出幼苗最佳培养基配方为1/2MS+3%蔗糖+0.7%琼脂+0.5g/LPVP+1.0mg/LKT+0.01mg/L2,4-D;另外,使用1/2MS+3%蔗糖+0.7%琼脂+0.5g/LPVP+0.5mg/L2,4-D做继代培养可以使愈伤组织持续增殖。[结论]研究直接使用野外材料组织培养,简化了试验步骤,是一种方便快速的蜈蚣草组培方法。
