Influence of sampling position and growth rate on the wood properties of Benguet pine (Pinus kesiya Royle ex. Gordon) [Philippines].

Tavita Y.L.
Variation in growth rate and wood properties was studied on disks taken at breast height from 15 randomly selected Benguet pine trees growing in a plantation. Growth rate expressed in terms of ring width did not significantly affect wood features such as specific gravity, percent latewood and fiber cross-sectional dimensions, but significantly affected tracheid length and extractive content in a negative manner. The strong effects of ring number from the pith to the bark on most of the wood features were likewise noted. A systematic pattern of variation appeared to exist based on pooled data. In terms of degree of interrelationship of the different wood quality indicators, there was a strong positive correlation between specific gravity and percent latewood. A negative correlation between specific gravity with tracheid diameter and lumen width was also observed. Tracheid length was highly correlated with tracheid diameter and lumen width; tracheid diameter with lumen width, and lumen width with cell wall thickness.
