Other claims from this paper (18)

Observation Plantation pine diameter growth was more than four times faster than natural growth.
Observation Plantation pine length growth was about three times natural growth.
Observation Plantation tracheids were about 31% longer.
Observation Plantation early-wood tracheids were 11% larger.
Observation Plantation latewood tracheids were 28% larger.
Observation Plantation latewood percentage was 28% lower.
Observation Plantation density was 2% lower.
Observation Overall strength properties were about the same.
Observation At corresponding rings plantation wood was generally heavier and stronger.
Observation From pith outward, tracheid length and ring width decreased.
Observation Outside the first few years, tracheid diameter, latewood percentage and cell wall percentage varied little and irregularly.
Observation Plantation density and strength peaked at growth rings 9 to 18.
Observation Natural-grown density and strength peaked at rings 30 to 70.
Observation Tracheid length increased upward along the stem.
Observation Strength generally decreased upward, with a natural-grown maximum at 5.3 to 7.3 m.
Association Resin canal number was directly proportional to ring width.
Observation Resin canals were mostly in summerwood and transition regions.
Association Plantation wood density increased outward with age from pith, independent of ring width.

M.L. De Vries; S.A. Wilde Netherlands Journal of Agricultural Science 1962. doi:10.18174/njas.v10i3.17594

Other claims from this paper (5)

Observation The water supply in the 4-ft root zone of thinned red pine plantations averaged nearly 10% (500 tons/acre).
Observation The soil of red pine stands gained moisture from midsummer rainfall.
Observation The fully-stocked red pine stand had high soil moisture early in the growing season because of a delayed thaw.
Intervention effect 50% thinning reduced the growing stock of red pine beyond permissible limits.
Intervention effect 50% thinning was favourable to weed growth in red pine stands.
