The Cuauhtemoc earlywood
chronology was used to reconstruct June-July PDSI values for east-central Mexico (i.
Count the rings in each tree cookie: Count each transition from dark latewood to light earlywood
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
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.
The impacts on drying behavior of basic density, initial moisture content, percentage and position of heartwood, ring count, rings from the pith, growth ring angle, and earlywood
and latewood coverage on board faces were investigated for western hemlock (Tsuga heterophylla) lumber.
Blocks were cut from one earlywood
and one latewood area (10 x 10 [mm.
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).
Preweathering increases latewood adhesion of film-forming finishes and decreases earlywood
