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...

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...

Effect of light quality and periodicity upon germination of Douglas-fir seed (Pseudotsuga menziesii (Mirb.) Franco) and on growth of Douglas-fir seedlings

Creator:: Johnson, Le Roy Curtis
Abstract:: A study on the effects of light quality and periodicity on the germination of Douglas-fir seed and the growth of Douglas-fir seedlings was conducted. Interest was focused on responses that could be measured and observed without biochemical assay. It was found that .Douglas-fir seed,s would respond to red-light treatments by...

Comparative rates of CO₂ production from the forest floor in the Douglas-fir ecosystem

Creator:: Phillips, Michael John
Abstract:: To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...

Natural and artificial regeneration of whiteleaf manzanita in competition studies

Creator:: Newton, Michael, 1932-, White, Diane E., and Oregon State University. Forest Research Laboratory
Abstract:: At three sites in southwest Oregon, uniform stands of whiteleaf manzanita were created for future studies on the effects of manzanita competition on Douglas-fir and ponderosa pine plantations. The sites were marked according to grids and nearby 2-year-old seedlings were lifted and transplanted to fill in gaps in the natural...
