Creator:: Lens, Frederic, Cooper, Laurel, Gandolfo, Maria Alejandra, Groover, Andrew, Jaiswal, Pankaj, Lachenbruch, Barbara, Spicer, Rachel, Staton, Margaret E., Stevenson, Dennis W., Walls, Ramona L., and Wegrzyn, Jill
Abstract:: A wealth of information on plant anatomy and morphology is available in the current and historical literature, and molecular biologists are producing massive amounts of transcriptome and genome data that can be used to gain better insights into the development, evolution, ecology, and physiological function of plant anatomical attributes. Integrating...

Creator:: Lachenbruch, Barbara
Abstract:: Student activities and instructor-made models are described to facilitate and encourage other instructors to develop their own appropriate activities and models for teaching the three-dimensional structure of wood. The teaching activities include making several annual rings with straws pushed into clay, drawing wood’s structure onto a piece of paper that...

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...

Creator:: Lei, Hua, Milota, Michael R., and Gartner, Barbara L.
Abstract:: In order to analyze the variation in wood properties within and between trees of an underutilized tree species, we sampled six Oregon white oak (Quercus garryana Dougl.) trees from an 80-year-old mixed stand of Q. garryana and Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) in the Coast Range of Western Oregon, USA....

Abstract:: The cohesion-tension theory of water transport states that hydrogen bonds hold water molecules together and that they are pulled through the xylem under tension. This tension could cause transport failure in at least two ways: collapse of the conduit walls (implosion), or rupture of the water column through air-seeding. The...

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...

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...

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,...
