摘要： 小麦生态试验(石家庄点)结果表明,在不同年度和播期中,冬型小麦品种的子粒蛋白质含量有显著差异.春播样品的蛋白质含量比秋播的高.气候条件对子粒蛋白质含量有着重要的影响.开花至成熟期间的日平均温度较高,夜温较高,日长较长等条件都可以促进子粒蛋白质含量的提高.这期间的日平均温度是主要影响因素.

Abstract: The results of ecological experiments for the wheat in 1983-1985 at Shijia-zhuang indicated that the some varieties of winterness wheat greatly differed in the protein contents of the grains in various sowing times-of the year. The protein contents in grains of spring wheat were higher than that of winter wheat. The climatic conditions exerted greatly influence to the protein contents in wheat grains.Higher average day temperature, higher night temperature and longer daytime in period from florescence to maturation could raisethe protein contents in wheat grains. The average day temperature in this period is a determinant factor for the protein contents.
