Predicting the chemical composition of juvenile and mature woods in Scots pine (Pinus sylvestris L.) using FTIR spectroscopy

Popis výsledku v původním jazyce

The chemical composition of wood is one of the key features that determine wood quality. The focus of this study was on identifying differences between juvenile and mature woods in Scots pine (Pinus sylvestris L.) and developing models for predicting the chemical composition of these two wood types. Chemical traits, determined by traditional wet chemistry techniques, included the proportion of lignin, polysaccharides and extractives. Partial least squares regression of Fourier transform infrared (FTIR) spectra was used for model building. The model performance was primarily evaluated by root mean squared error of predictions (RMSEP). High predictive power was attained for the content of lignin (RMSEP of 0,476 and 0,495 for juvenile and mature woods, respectively) and extractives (0,302 and 0,471), good predictive power for cellulose (0,715 and 0,696) and hemicelluloses in juvenile wood (0,719) and low predictive power for hemicelluloses in mature wood (0,823). A distinct band was observed at 1693 per
