Effects of release from suppression on wood functional characteristics in young Douglas-fir and western hemlock

Creator:: Renninger, Heidi J., Gartner, Barbara L., and Meinzer, Frederick C.
Abstract:: Little is known of wood properties in trees that were initially suppressed and subsequently released from suppression. The purpose of this study was to assess differences in growth ring width, specific conductivity (Ks), tracheid dimensions, moisture content, and wood density in suppressed Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western hemlock...

Hydraulic safety margins and embolism reversal in stems and leaves: Why are conifers and angiosperms so different?

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Angiosperm and coniferous tree species utilize a continuum of hydraulic strategies. Hydraulic safety margins (defined as differences between naturally occurring xylem pressures and pressures that would cause hydraulic dysfunction, or differences between pressures resulting in loss of hydraulic function in adjacent organs (e.g., stems vs. leaves) tend to be much...

Development of Douglas-fir seedling root architecture in response to localized nutrient supply

Creator:: Jacobs, Douglass Frederick, Rose, Robin, and Haase, Diane L.
Abstract:: Three months following sowing, Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were transplanted into pots with controlled-release fertilizer (CRF) applied at rates of 0, 8, 16, and 24 g/2200 cm3 soil as a single uniform layer beneath the root system. Seedlings were destructively harvested periodically, and roots were divided into vertical...

Potential for Using Essential Oils to Protect Viscoelastic Thermal Compression–Treated Hybrid Poplar

Creator:: Scouse, Adam, Kamke, Frederick A., and Morrell, Jeffrey J.
Abstract:: The potential for using pretreatment with cinnamon leaf oil or juniper foliage oil to improve the durability of viscoelastic thermal compression (VTC)–treated hybrid poplar was explored in a field termite test and a laboratory mold test. The addition of oils prior to VTC processing had variable effects on resistance to...

Influence of the thermo-hydro-mechanical treatments of wood on the performance against wood degrading fungi

Creator:: Lesar, Bostjan, Humar, Miha, Kamke, Frederick A., and Kutnar, Andreja
Abstract:: Hybrid poplar (Populus deltoides × Populus trichocarpa) and Douglas-fir (Pseudotsuga menziesii) wood specimens were densified with three variations of Thermo-Hydro-Mechanical (THM) treatment. The THM treatments differed in the steam environment, including transient steam (TS), saturated steam (SS), and saturated steam with 1 minute post-heat-treatment at 200°C (SS+PHT). The bending properties,...

Microstructure of viscoelastic thermal compressed (VTC) wood using computed microtomography

Creator:: Standfest, Gernot, Kutnar, Andreja, Plank, Bernhard, Petutschnigg, Alexander, Kamke, Frederick A., and Dunky, Manfred
Abstract:: The paper describes for the first time the analysis of the structure of compressed wood using computed tomography. The anatomical structures of Douglas-fir and hybrid poplar before and after densification with the Viscoelastic Thermal Compression (VTC) process were described by pore size distributions and mean pore sizes and compared. The...

A key to the literature on forest growth and yield in the Pacific Northwest, 1910-1981

Creator:: Hann, David W., Riitters, K. H. (Kurt H.), and Oregon State University. Forest Research Laboratory
Abstract:: Tables are presented that summarize 108 published articles on forest growth and yield in the Pacific Northwest. Each table describes the form of the information presented, the species to which the information is applicable, the data sources used to develop the information, the data needed to predict growth and yield,...
