Ability of selected fungi from Douglas-fir poles to degrade wood and their tolerance to wood-preserving chemicals

Creator:

Safo-Sampah, Stephen

Abstract:

Wood degrading ability and tolerance to wood-preserving chemicals of several fungi isolated from Douglas-fir utility poles were investigated by the agar-stick and soil-block methods. Birch (Betula. sp. ) wood sticks and western hemlock (Tsuga heterophylla) wood blocks were used. The soil-block and agar-stick tests provided identical weight loss rankings of...

The influence of seed source origin and phenological characteristics on wood quality in a young Douglas-Fir Provenance Plantation

Creator:

Robinson, Walter P.

Abstract:

The relationships of several wood quality traits with seed origin and phenological characteristics, measured at a young age, were tested from six seed sources in a young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) provenance plantation. The wood quality traits measured were wood density, uniformity of wood density, percentage latewood, fiber length,...
