摘　　要：氮肥用量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;随着氮肥用量增加,籽粒蛋白质含量、B醇溶蛋白和C醇溶蛋白组分含量显著增加,D醇溶蛋白组分含量增加相对较少。品种对籽粒蛋白质含量、C和D醇溶蛋白组分含量的影响要比氮肥用量大,而B醇溶蛋白组分含量的差异主要是由氮肥用量的差异引起的。氮肥用量显著影响千粒重和β-淀粉酶活性,而对产量的影响不显著;随着氮肥用量增加,千粒重和β-淀粉酶活性显著增加,而产量的变化相对较小。品种对千粒重和β-淀粉酶活性的影响要比氮肥用量大。本研究中未发现β-淀粉酶活性和籽粒蛋白质含量之间的正相关关系。Grain protein content, B and C hordein content were dramatically affected by application rate of nitrogen fertilizer,whereas D hordein content was little affected. Grain protein, B and C hordein contents increased significantly with the application rate of nitrogen, whereas D hordein content had less increase. The effect of cultivar on grain protein, C and D hordein contents was larger relative to that of nitrogen treatment. The variation of B hordein content was mainly attributed to nitrogen treatment. Grain weight and beta-amylase activity were significantly affected by nitrogen ~nt, but grain yield had little change over three N levels. The positive correlation relationship between beta-amylase activity and grain protein content was not detected in this study.
