本文利用灰色关联分析方法对15个小麦品种的蛋白质与若干加工品质性状、沉淀值与粉质仪测定值、不同氨基酸与蛋白质的关系进行了研究。结果表明:在出粉率、湿面筋、沉淀值和白度这几个品质性状中,以出粉率与蛋白质的关联度最大,以沉淀值与蛋白质的关联度最小;6个粉质仪测定值中,以稳定时间、评价值、带宽与沉淀值关联度最大,而面团形成时间与之关联度较小。15种氨基酸与蛋白质的关联度相似,人体必需的8种氨基酸大多与蛋白质关系密切。另外,本文还对灰色关联分析方法在研究作物性状间相互关系的应用问题作了讨论。
In this paper, the relationship between protein and some processing quality traits, sedimentation value and determination of powdery mildew instrument, different amino acids and proteins of 15 wheat cultivars were studied by gray relational analysis. The results showed that among the quality traits such as flour yield, wet gluten, sedimentation value and whiteness, the correlation between flour yield and protein was the highest, and the sedimentation value and protein were the least. Value, the stability time, evaluation value, bandwidth and precipitation value of the most relevant, while the dough formation time associated with the smaller. 15 kinds of amino acids and protein relevance is similar to the human body most of the eight kinds of amino acids and proteins are closely related. In addition, this paper also discusses the application of gray relational analysis in the study of the relationship between crop traits.
