摘　　要：氮肥施用时期显著影响籽粒蛋白质含量、B醇溶蛋白和C醇溶蛋白组分含量,而对D醇溶蛋白组分含量的影响不显著;与前期施氮相比,后期施用氮肥显著增加籽粒蛋白质和三种醇溶蛋白组分的含量。品种对B、C醇溶蛋白含量的影响要比氮肥施用时期大,而籽粒蛋白质和D醇溶蛋白含量的差异主要是由氮肥施用时期的差异引起的。生育后期施用氮肥增加β-淀粉酶活性。Grain protein, B and C hordein contents were dramatically affected by application timing of nitrogen fertilizer, whereas D hordein content was little affected. The treatment With N application at late stage had significantly higher protein and hordein fraction contents than the treatment with N application at early growth stage. The effect of cultivar on B and C hordein contents was larger than that of nitrogen application time, whereas the variations of grain protein and D hordein contents were mainly attributed to the application timing of nitrogen. The treatment with N application at late stage had higher beta - amylase activity in comparison with the treatment with N application at early stage.
