Patterns of xylem variation within a tree and their hydraulic and mechanical consequences

Creator:: Gartner, Barbara L.
Abstract:: Xylem is nonuniform in its structure and function throughout the plant stem. Xylem structure varies from pith to bark, from root to apical meristem, from stem to branch, at nodes vs internodes, and at junctions of branches, stems or roots compared to the internodal regions nearby. At smaller scales, anatomy...

Is long primary growth associated with stem sinuosity in Douglas-fir?

Creator:: Gartner, Barbara L. and Johnson, G. R.
Abstract:: Stem sinuosity is a highly visible stem-form trait in the leaders of fast-growing Douglas-fir (Pseudotsuga menziesii var. (Mirb.) Franco) trees, yet its cause is unknown. We tested the hypotheses that sinuous stems have longer expanses of primary growth than nonsinuous stems (putting the leader at higher risk curvature, induction of...

Effects of silvicultural practices on carbon stores in Douglas-fir – western hemlock forests in the Pacific Northwest, U.S.A.: results from a simulation model

Creator:: Harmon, Mark E. and Marks, Barbara
Abstract:: We used a new model, STANDCARB, to examine effects of various treatments on carbon (C) pools in the Pacific Northwest forest sector. Simulation experiments, with five replicates of each treatment, were used to investigate the effects of initial conditions, tree establishment rates, rotation length, tree utilization level, and slash burning...

Effect of growth ring orientation and placement of earlywood and latewood on moe and mor of very-small clear Douglas-fir beams

Creator:: Grotta, A. T., Leichti, R. J., Gartner, Barbara L., and Johnson, G. R.
Abstract:: ASTM standard sizes for bending tests (either 50 × 50 mm or 25 × 25 mm in cross-section) are not always suitable for research purposes that characterize smaller sections of wood. Moreover, the ASTM standards specify loading the sample on the longitudinal-tangential surface. If specimens are small enough, then the...

Impact of the foliar pathogen Swiss needle cast on wood quality of Douglas-fir

Creator:: Johnson, G. R., Grotta, Amy T., Gartner, Barbara L., and Downes, Geoff
Abstract:: Many stands of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) near coastal areas of Oregon and Washington are heavily infected with the foliar pathogen causing Swiss needle cast (SNC) disease, and yet there is very little research on the resulting wood quality. Modulus of elasticity (MOE), modulus of rupture (MOR), microfibril angle...

The effects of silvicultural activities on wildlife and fish populations in Oregon and the Pacific Northwest : an annotated bibliography from 1960-1999

Creator:: Maas-Hebner, Kathleen G. (Kathleen George), Schrader, Barbara A., and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography was compiled to provide forest managers with a comprehensive list of sources on the potential effects of silvicultural activities on wildlife and fish populations in Pacific Northwest forests. The bibliography emphasizes publications directly examining silvicultural activities and responses by these populations. Abstracts from 296 publications are indexed...

Wood density of young-growth western hemlock: relation to ring age, radial growth, stand density, and site quality

Creator:: DeBell, Dean S., Singleton, Ryan, Gartner, Barbara L., and Marshall, David D.
Abstract:: Breast-high stem sections were sampled from 56 western hemlock (Tsuga heterophylla (Raf.) Sarg.) trees growing in 15 plots representing a wide range of tree and site conditions in northwestern Oregon. Growth and wood density traits of individual rings were measured via X-ray densitometry, and relationships of ring density and its...

Wood density and hydraulic properties of ponderosa pine from the Willamette Valley vs. the Cascade Mountains

Creator:: Bouffier, Laurent A., Gartner, Barbara L., and Domec, Jean-Christophe
Abstract:: The Willamette Valley (WV) race of ponderosa pine (Pinus ponderosa) is being widely planted for timber in the Willamette Valley, western Oregon, because it grows in habitats that are either too wet or too dry for Douglas-fir (Pseudotsuga menziesii). Compared to the eastern Cascade Mountains (CM), the WV has 3...

Effect of extraction on wood density of western hemlock (Tsuga heterophylla (Raf.) Sarg.)

Creator:: Singleton, Ryan, DeBell, Dean S., and Gartner, Barbara L.
Abstract:: Extractives can account for between 1 to 20% of the oven-dry weight of wood of various tree species and can influence wood density values appreciably. Removing these chemical deposits (extraction)in wood samples can help establish a consistent baseline for comparing wood densities where extractives are expected to differ between sample...
