RASCON-SOLANO, Joel et al. Yield and Distribution of Sawn Wood Classes of Pines from Northern Mexico. Colomb. for. [online]. 2023, vol.26, n.2, pp.60-76.  Epub 01-Ago-2023. ISSN 0120-0739.  https://doi.org/10.14483/2256201x.20082.

This research aimed to determine the yield of sawn wood and the distribution of pine classes depending on the species, size, and quality of the log. 101 pine logs classified with NMX-C-359-1988 were analyzed, collecting data on species, class, diameter, taper, and length. The products obtained were counted and classified with NMX-C-224-ONNCCE-2001 in order to determine the volumetric yield per log. Homogeneity of variance, ANOVA, Shapiro-Wilk, and Pearson's correlation tests were performed at a significance ≤ 0.05. It was found that, the larger the diameter of the log and the smaller the taper, the yield per class of sawn wood increases. Log quality exhibits a highly significant effect on sawn wood quality. The aforementioned variables are good predictors to estimate the volumetric yield and proportion of sawn pine wood classes.
