Natural Resources Management and Environmental Sciences
The effects of dwarf mistletoe (Arceuthobium americanum Nutt. ex. Engelm.) on the wood properties of lodgepole pine (Pinus contorta Dougl.) were studied. The results indicate: a decline in modulus of elasticity, modulus of rupture, and work to proportional limit in both infected and noninfected wood from the infected trees; a higher specific gravity of the infected wood; a higher percentage of alcohol-benzene extractives in the infected wood; an increase in longitudinal shrinkage in both infected and noninfected wood from the same tree; a lower percentage of latewood in wood from infected trees; no significant difference in growth ring …
