小麦籽粒品质除品种特性的基本差异外,随施肥量的增加,多数品质项目指标提高,然而清蛋白、谷蛋白、淀粉含量却有降低趋势,蛋白质产量、直链淀粉含量还受施氮肥期的影响,湿面筋含量、面筋持水率、面条煮熟增重率等,在一定程度上受播期的影响,随播期推迟而增加,小麦籽粒多项品质指标间存在一定相关关系。 In addition to the basic differences in the characteristics of wheat varieties, with the increase of fertilizer application, the indexes of most quality items increased. However, the content of albumin, glutenin and starch decreased while the yield of protein and amylose content also increased Affected the content of wet gluten, gluten water holding capacity and noodle cooking weight gain rate, which was affected to some extent by sowing date and increased with the delay of sowing date. There were some correlations among the quality indexes of wheat grain.
