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...

Wind-shelters as safe sites for establishment of Lupinus arboreus, a coastal species

Creator:: Gartner, Barbara L.
Abstract:: To learn the effect of wind on a species native to a windy site, I compared germination, seedling survival, seedling form, and the force required to uproot seedlings in a wind-exposed and a wind-sheltered site. In February 1992, the sand dune perennial Lupinus arboreus Sims. was planted in wind-exposed and...

Does photosynthetic bark have a role in the production of core vs. outer wood?

Creator:: Gartner, Barbara L.
Abstract:: This paper hypothesizes a correlation in some species between the cambial age of transition from core (juvenile) to outer (mature) wood and the cambial age of transition from photosynthetic to non-photosynthetic bark. Secondly, this paper hypothesizes that the relationship is causal: a signal produced in relation to the photosynthetic bark...

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,...

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...

Effects of stand density on the growth of young Douglas-fir trees

Creator:: Woodruff, David R., Bond, Barbara J., Ritchie, Gary A., and Scott, William
Abstract:: The objectives of this study were (i) to provide further evidence of a positive correlation of stand density with early growth of coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii); (ii) to determine when after planting the positive growth response occurs and how long it lasts; and (iii) to use...

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...

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...

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...

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...
