研究了不同浓度外源激素6-BA对啤酒大麦品种陇啤1号、Sebastion、Hays产量和品质的影响，结果表明，不同浓度的6-BA对啤酒大麦的农艺性状和品质均有影响，当浓度为10 mg/L时，3个品种的千粒重、产量、库尔哈巴值最高，蛋白质含量最低。说明外源激素6-BA能够提高啤酒大麦产量，改善啤酒大麦品质。

The effects of different concentrations exogenous hormone 6-BA on yield and quality of malt barley variety Longpi 1， Sebastion， Hays is studied. The result shows that had an influence on the agronomic trait and quality of malt barley with the increased of 6-BA concentration，with the concentrations is 10 mg/L， thousand seed weight，yield and kurt khabarov value of 3 varieties is the highest， on the contrary， the protein is the lowest.
