摘　　要：为研究旱碱胁迫对小麦产量和品质的影响,本研究对比了种植于旱碱地及非旱碱地7个小麦品种的产量、千粒重、容重、出粉率、蛋白质含量、湿面筋含量、粉质参数等指标。结果表明,受旱碱的影响,品种平均产量、千粒重、容重和弱化度分别下降了27.32%、9.21%、2.82%和38.27%,平均干面筋含量,面团的形成时间、稳定时间和粉质质量分别提高了9.21%、48.39%、479.31%和68.00%;平均出粉率和吸水率分别下降了4.89、2.02个百分点,平均蛋白质和湿面筋含量分别提高了2.30、2.64个百分点。上述结果表明,旱碱胁迫会降低小麦产量及面粉吸水率,但同时会提高小麦的蛋白质、面筋含量及面团形成时间、稳定时间和粉质质量。本研究可为旱碱地小麦品种的应用和品种改良提供一定的依据。To study the influence of drought and alkali stress on yield and quality of wheat,the yield,thousand kernel weight,bulk density,flour yield,protein content,wet gluten content and farinogenic parameters of 7 wheat varieties planted in alkaline soil and non-alkaline soil were compared.The results showed that under the influence of drought and alkali stress,the average yield,thousand-kernel weight,bulk density,and dough weakening degree of the varieties decreased by 27.32%,9.21%,2.82%,and 38.27%,respectively.Meanwhile,the average dry gluten content,dough development time,stability time,and farinograph quality index increased by 9.21%,48.39%,479.31%,and 68.00%,respectively.The average flour yield and water absorption rate decreased by 4.89 and 2.02 percentage,respectively,while the average protein and wet gluten content increased by 2.30 and 2.64 percentage,respectively.The results showed that the yield and water absorption of wheat flour were decreased,but the protein content,gluten content,dough formation time,stability time and flour quality were increased.This study can provide data basis for the application and improvement of wheat varieties in arid-alkali soil.
