摘　　要：目的大田条件下,研究几种植物生长调节剂对盾叶薯蓣根茎中薯蓣皂苷元含量及根茎产量的影响。方法采用单因素施肥方法,结果采用SPSS 17.0统计软件包进行分析。结果发现施用萘乙酸、多效唑、烯效唑和2,4-D均可大大提高盾叶薯蓣根茎产量,但对于薯蓣皂苷元含量的影响较小。对薯蓣皂苷元含量的影响,2,4-D>膨大素>NAA>稀效唑>多效唑;对盾叶薯蓣根茎产量的影响,2,4-D>NAA>多效唑>稀效唑>膨大素。结论喷施一定浓度的2,4-D,对优质、高产盾叶薯蓣的栽培,具有重要的实践意义。OBJECTIVE A field experiment was conducted to investigate the different effects of various plant growth regulators on diosgenin contents and rhizome yields of Dioscorea zingiberensis. METHODS Experiments were conducted with one factor design, and data were analyzed statistically on SPSS 17.0. RESULTS Compared with the control, the rhizome yields were significantly increased by applying with 2, 4-D, NAA, paclobutrazol and uniconazole, but the contents of diosgenin was not obviously influenced by them. The degree of effect on diosgenin content is ranged with 2, 4-D, Pengdasu, NAA, uniconazole, paclobutrazol, while the outputs of dioscorea rhizome is 2, 4-D,NAA, paclobutrazol , uniconazole, Pengdasu. CONCLUSION 2,4-D can increase the diosgenin contents and rhizome yields ofDioscorea zingiberensis
