Sapwood and inner bark quantities in relation to leaf area and wood density in Douglas-fir

Creator:: Gartner, Barbara L.
Abstract:: The relationships between leaf area and sapwood and inner bark quantities (widths, areas, and volumes) were studied in an attempt to understand the design criteria for sapwood quantity in eighteen 34-year-old Douglas-fir (Pseudotsuga menziesii) trees with a wide range of leaf areas, sapwood areas, and dry masses of leaf, xylem,...

Discrete Ordinates Radiation Transport using High-Order Finite Element Spatial Discretizations on Meshes with Curved Surfaces

Creator:: Woods, Douglas N.
Abstract:: We spatially discretize the Sn transport equation using the high-order (HO) discontinuous finite element method (DFEM) on HO meshes. Previous work provided a proof-of-concept for this spatial discretization method in X-Y geometry. Included in the present work, we derive a spatial discretization for the Sn transport equation in both X-Y...

High Order Finite Elements SN Transport in X-Y Geometry on Meshes with Curved Surfaces in the Thick Diffusion Limit

Creator:: Woods, Douglas N.
Abstract:: The high-order finite element S[subscript N] transport equations are solved on several test problems to investigate the behavior of the discretization method on meshes with curved edges in X-Y geometry. Simpler problems ensured the correct implementation of MFEM, the general fi nite element library employed. A convergence study using the...

How well do American viticultural areas correspond with the soil classes in Oregon's northern Willamette Valley? A question for the wine industry

Creator:: Wood, Douglas T.
Abstract:: The specific geography of individual wine growing regions has long been understood to be a significant factor in predicting both a region’s success in producing high quality grapes, and the resulting demand for wines produced from that region's fruit. In the American wine industry, American Viticultural Areas (AVAs) are increasingly...

Interactions of ammoniacal copper zinc arsenate (ACZA) wood preservative with Douglas-fir

Creator:: Lebow, Stan T.
Abstract:: The use of the waterborne wood preservative, ammoniacal copper zinc arsenate (ACZA), is likely to increase in the near future because of environmental concerns associated with oilborne preservatives. Developing an understanding of the permanence of this preservative in wood will become important from both environmental and performance standpoints. Conventional thinking...

Effects of release from suppression on hydraulic architecture, photosynthetic capacity and functional wood characteristics in Douglas-fir and western hemlock

Creator:: Renninger, Heidi
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), a shade intolerant species, and western hemlock (Tsuga heterophylla (Raf.) Sarg.), a shade tolerant species, were compared to learn more about the temporal pattern of release from suppression in both species, whether hydraulic architecture or photosynthetic capacity constrain release and how wood functional properties change...

No correlation between latewood formation and leader growth in Douglas-fir saplings

Creator:: Renninger, Heidi J., Gartner, Barbara L., and Grotta, Amy T.
Abstract:: The width of earlywood and latewood in conifer xylem may have a profound effect on water transport and storage, vulnerability to embolism, and wood strength, yet the controls over the timing of latewood formation are unclear. Tracheids differentiating in the cambial zone are influenced by IAA indole-3 acetic acid, the...

Influence of red alder competition on cambial phenology and latewood formation in Douglas-fir

Creator:: Grotta, A. T., Gartner, Barbara L., Radosevich, S. R., and Huso, M.
Abstract:: To better understand the influence of competition on wood formation and wood quality in Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco), patterns of cambial growth and latewood production were examined for one growing season in 15-year-old plantations with similar densities but differing Douglas-fir/red alder (Alnus rubra Bong.) ratios. The treatments consisted of...

Distribution and vitality of xylem rays in relation to tree leaf area in Douglas-fir

Creator:: Gartner, Barbara L., Baker, D. C., and Spicer, R.
Abstract:: The factors that determine sapwood width and volume in a tree are not known. This study asked whether sapwood width is related to a need for stem storage sites. Experiments were conducted on 12 34-year-old Douglas-fir [(Pseudotsuga menziesii (Mirb.) Franco] trees with a 6-7 fold range of leaf areas and...
