Nondestructive estimation of tracheid length from sections of radial wood strips by near infrared spectroscopy
The use of calibrated near infrared (NIR) spectroscopy for
predicting tracheid length of Pinus taeda L. (loblolly pine)
wood samples is described. Ten-mm sections of 14 P. taeda radial strips were selected and NIR spectra
obtained from the radial longitudinal face of each section.
The fibers in these sections were characterized in terms
of arithmetic and length-weighted mean tracheid length
using a fiber quality analyzer, and calibrations with NIR
spectra were developed for both measures of tracheid
length. Relationships were good, with coefficients of
determination (R2) of 0.88 for arithmetic tracheid length
and 0.96 for length-weighted tracheid length. The accuracy
of NIR predicted length-weighted tracheid length
was sufficient for ranking purposes.
