Filtering by: Subject Wood poles -- Measurement Advisor Corden, Malcolm E.

The development and use of breaking radius and impact bending tests for measuring wood strength loss caused by basidiomycetes isolated from air-seasoning Douglas-fir

Creator:

Sexton, Camille Marie

Abstract:

Douglas-fir utility poles are routinely air seasoned before treatment with chemical preservatives. Basidiomycetous fungi invade these poles and may cause strength loss during air seasoning or later if treatment temperatures are insufficient to kill the decay fungi. The purpose of this study was to develop a rapid test to asses...

Establishment of Poria carbonica in wood and colonization by basidiomycetes of Douglas-fir utility poles during air seasoning

Creator:

Przybylowicz, Paul

Abstract:

Influence of temperature and wood moisture content on spore germination and colonization of Douglas-fir (Pseudotsuga jnenziesii) heartwood by Poria carbonica basidiospores and chlamydospores was studied. Both spore types germinated and colonized wood at moisture contents above the fiber saturation point, but not below. Germination and wood colonization occurred at 22°C...
