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 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,...
