近红外法测定小麦品质的准确性分析

Accuracy Analysis of Wheat Quality Characteristics by Near-Infrared Spectrometer

摘要: 为了检验近红外测定小麦品质的准确性，对30份小麦样品进行近红外法和国标化学法检测。相关性分析显示，两种检测方法获得的蛋白质和湿面筋数据都呈极显著相关(P < 0.01)，相关系数分别为0.951和0.845，说明近红外法可代替国标化学法检测小麦蛋白质含量，近红外法测量的湿面筋含量可作为参考数据用于育种初筛。

Abstract: The quality characteristics of thirty wheat varieties were tested by near-infrared spectrometer (NIRS) and national standard chemical method to verify the accuracy of NIRS method. The correlation analysis showed that protein content and wet gluten content obtained by two methods were significantly correlated (P < 0.01). The correlation coefficients were 0.951 and 0.845 respectively. The results indicated that the NIRS method could replace national standard chemical method to detect wheat protein content. And wet gluten content measured by the NIRS method could be used as reference data for preliminary screening in wheat breeding.
