Prediction of cellulose, hemicellulose, hollocelulose and lignin content by multivariate models with FT-IR (PLS) in Capirona (C. spruceanum).
A: Cellulose, B: Hemicellulose, C: Holocellulose and D: Lignin. : coefficient of determination of calibration. RMSEP: root mean squared error of predictions. RPD: ratio of performance to deviation. Solid line: regression line of calibration set. Dashed line: regression line of validation set.
