摘要：Michelia macclurei Dandy is a valuable plantation species, and its wood is employed extensively in buildings and furniture. In this study, the radial variations in density, crystallinity index and microfibril angle were investigated via XRD and near-infrared spectroscopy. Models were constructed in order to predict the crystallinity and microfibril angle of Michelia macclurei wood. The density and crystallinity exhibited a gradual increase from the pith to the bark, while the microfibril angle demonstrated a gradual decrease. For the collected near-infrared spectrum, "MSC + 1st in the 780-1500 nm spectral range" and "MSC in the spectral range of 780-2500 nm spectral range" were identified as the optimal preprocessing methods for crystallinity and microfibril angle. The correlation coefficients of the crystallinity and microfibril angle calibration models were 0.91 and 0.95, respectively, while the correlation coefficients of the prediction models were 0.91 and 0.98, respectively. The model established in this study allows for rapid and non-destructive prediction of the crystallinity and microfibril angle of Michelia macclurei wood. The findings from this study provide valuable and detailed scientific data that can contribute to the study and prediction of wood properties. ? 2024 Informa UK Limited, trading as Taylor & Francis Group.
