Title: Fibril angle of loblolly pine wood as related to specific gravity, growth rate, and distance from pith

Publication Series: Miscellaneous Publication
Description: Fibril angles were greater for earlywood (avg. 33.4o) than for latewood tracheids (avg. 26.9o). For earlywood, fibril angle did not differ between growth rates when the specific gravity was low (avg. 33.3o). When the specific gravity was high, wood of fast growth had a higher fibril angle (avg. 35.1o) than wood of slow growth (avg. 32.0o). No differences were detected between core, middle, and outer wood. In the latewood tracheids, fibril angles were greater in corewood (avg. 28.0o) than in middle or outer wood (Avg. 26.3o). For whole wood (a weighted average of earlywood and latewood), fibril angle averaged 30.7o and was greater in corewood (avg. 32.2o) than in middle or outer wood (avg. 29.9o).
