| Abstract: | In this paper, near-infrared spectroscopy quantitative analysis of samples of flue-cured tobacco and wheat is discussed using principal components-all possible regression (PCR-SR).The study shows the calibration models for the determination of total sugare,reducing sugars in flue-cured tobacco and for protein in wheat have good predictive results,and the calculation results of principal component-all possible regression are as good as the results of partial least square method. |
