Wood teak quality from plantations. Imput of near-infrared spectroscopy tool
Quality control of the planting material is essential to guarantee the reliability and the future of teak plantation. Outcomes from Cirad collaborative researches on teak genetic improvement including selection on wood traits combined with the development of efficient nursery and in vitro propagation methods have led to the availability of superior quality planting material. Near-infrared spectroscopy (NIRS) is useful for estimating chemical and physicomechanical wood properties. Fibre saturation point and natural durability classes estimated by standard methods of teak wood samples from Malaysia-Sabah and Africa (Togo, Ivory Coast, Ghana) were correlated by partial least squares regression with NIRS spectra data taken on the same samples. Predicted values from NIRS calibration models were compared to measured ones with success and associated with core sampling this approach will allow us to predict these traits of a large number of wood samples from different origin in short times.
