From: FTIR-ATR-based prediction and modelling of lignin and energy contents reveals independent intra-specific variation of these traits in bioenergy poplars

Figure 4

External validation of the PLSR models for lignin (A) and energy contents (B) prediction. FTIR-ATR spectra were produced for an independent set of wood samples and used to predict the lignin or energy contents using the best models from table 1 and 2, respectively. Lignin and energy contents were determined by the acetyl bromide method and a combustion calorimeter, respectively. The predicted values were plotted against the measured values. Solid line represents regression line of best fit between measured and predicted values.
