Douglas-fir: The Genus Pseudotsuga

Creator:: Lavender, Denis P. and Hermann, Richard K.
Abstract:: Douglas-fir (Pseudotsuga menziesii) has a wide distribution in North America and is one of the tree species most widely distributed outside its natural range. The species has been introduced to Europe, New Zealand, South America, and elsewhere around the world. At present, Douglas-fir is an accepted and integral part of...

Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

Creator:: Pruyn, Michele L., Gartner, Barbara L., and Harmon, Mark E.
Abstract:: • A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...

Stability and density management in Douglas-fir plantations

Creator:: Hann, David W.
Abstract:: In their recent Canadian Journal of Forest Research Comment 368 article, Wilson and Oliver (2000) developed an equation for predicting the average ratio of height to diameter at breast height for the largest 250 trees/ha (H/DL250) in unthinned stands as a function of initial density and dominant height of the...

Pollen contamination trends in a maturing Douglas-fir seed orchard

Creator:: Adams, W. T., Hipkins, Valerie D., Burczyk, J., and Randall, W. K.
Abstract:: Pollen contamination was investigated in one block (block 4) of a 10-block Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seed orchard complex in western Oregon. Blocks (25 clones each) represent different breeding zones; thus, contaminant pollen sources not only included the adjacent natural stand of Douglas-fir, but also other blocks within the...

Relationship Between Specific Gravity and Percentage of Summerwood in Wide-Ringed, Second-Growth Douglas-Fir

Creator:: Smith, Diana M.
Abstract:: For the sample of wide-ringed Douglas-fir discussed in this report, the relationship between specific gravity and percentage of summerwood is linear over a range of 16 to 60 percent summerwood content of the annual ring. The specific gravity of the summerwood and springwood portions of 96 dissected annual rings is...
