| 摘 要： | 采用偏最小二乘回归法,对近红外光谱法测定玉米完整子粒粗淀粉含量的可行性进行研究。结果表明,定标集和检验集的预测值与化学测定值间均达极显著正相关,相关系数分别为0.9610和0.9820,并具有较小的定标标准差和预测标准差,分别为0.707和0.666。所建立的校正模型具有较高的预测精度。

| Abstract: | The study was conducted to investigate the feasibility of measuring crude starch contents in intact seeds of maize by near infrared reflectance spectroscopy(NIRS).The chemometric method of partial least square(PLS) regression was used.The result showed that there was a remarkable positive correlation between the predicted values and the chemical values.The correlation coefficients to chemical values in calibration set and validation set were 0.9610 and 0.9820,respectively.The standard error of calibration(S... |
