The measurement of each sample included four readings, two on earlywood, and two on latewood areas on three replicate specimens for each treatment-coating combination.
Latewood of both rings had higher [alpha]-cellulose, average fiber length, and coarseness than earlywood.
In addition, thinning significantly influenced earlywood and latewood tracheid length and cell dimension; fertilization significantly influenced cell dimension.
The wide ranges of mechanical properties in previous studies were often attributable to the ranges in juvenile wood percentage, specimen size differences, and purposeful attempts to isolate latewood or earlywood rings.
The numerous knots and grain deviation generated torn grain, while differences in density between earlywood and latewood brought raised grain.
By contrast, the surface roughness of pine is more or less representative for the total board surface, at least for the earlywood region as imaged in the pine scan.

Capillary absorption in Radiata pine wood has been shown to be lower in wood with high density (Booker and Kininmonth 1978), but in Norway spruce this effect is reduced by a lower aspiration ratio of bordered pits between tracheids in latewood than in earlywood (Liese and Bauch 1967b).
