Available in PDF, EPUB and Kindle. Book excerpt: "Spiral grain is a wood grain feature found sporadically in trees and has significant effect in sawn lumber and somewhat unknown effects in pulping. It does make up a portion of the harvested trees from a forest and therefore information relating to its fiber properties will be useful, particularly for pulping as its presence, if severe enough, typically renders the wood unusable for lumber. Spiral grain measurements and cores were made on 63 year old plantation white spruce (Picea glauca (Moench) Voss) grown in Northwestern Ontario. Occurrence of spiral grain was established for two different tree spacing treatments. The highest occurrence of spiral grain occurred in the widest spacing of 3.6 m x 3.6 m. Furthermore it was discovered that spiral grain seems to limit the diameter growth in trees."-- from abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Weekly bole measurements at 4.5 feet in height were made on individual codominant white spruce trees released on one, two, three, and four sides, and on untreated controls. Results showed that after 10 years annual circumference growth was still significantly related to the degree of release. The growth trend was established the first year but significant differences in annual growth were not evident until the third year. The growth rate reached a maximum during the ninth year. Trees with three and four sides released outgrew controls and trees with one and two sides released by a 2 to 1 ratio. Seasonal growth usually started around May 10, peaked during the second week in June, and ceased around August 20. Trees released on three or four sides appeared to start growing earlier and cease growing several days later than the other trees. The length of the growing season ranged from 100 to 115 days.
