Figure 2

Regression beta coefficient and variable importance plot (VIP) of PLS-DA models that discriminate TX08 (red), AR09 (blue), and AR10 (green) using centered and scaled Vis/NIR spectra with the selected predictive wavelengths indicated (A). Classification of TX08, AR09, and AR10 using PLS-DA models and percent variance explained (PVE) for each environment with regression line (red) (B). Canonical plot for linear discriminant analysis of TX08 vs. AR09 and AR10 using the 9 predictive wavelengths selected from the PLS-DA model (C), AR09 vs. TX08 and AR10 using the 8 predictive wavelengths selected from the PLS-DA model (D), and AR10 vs. TX08 and AR09 using the 3 predictive wavelengths selected from the PLS-DA model (E).
