✦ Synopsis

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