Height-related trends in structure and function of Douglas-fir foliage

Creator:: Woodruff, David R.
Abstract:: This dissertation investigated the impacts of tree height upon a range of physiological and structural characteristics of Douglas-fir foliage; relationships between structural and functional trends with height; and compensatory mechanisms that mitigate height-related growth constraints. Height-related trends in foliar physiological and anatomical characteristics were examined both within trees as well...

Hydraulic properties of compression wood in branches and reoriented shoots of Douglas-fir (Psuedotsuga menziesii)

Creator:: Spicer, Rachel
Abstract:: Xylem anatomy is a strong determinant of water transport efficiency and is therefore an important component of the overall hydraulic strategy of any woody plant. However, in addition to its role in water transport, xylem also serves in mechanical support, and these two functions may represent conflicting design requirements. To...

The starch content of roots and the osmotic concentration of expressed xylem sap as predictors of Douglas-fir seedling quality

Creator:: Forry, Keith R.
Abstract:: The goal of this study was to evaluate the ability of two seedling quality evaluation methods to predict the field survival of Douglas-fir (Pseudotsuga menziesii) seedlings. The starch reserves in seedlings have been suggested as a possible predictor of seedling quality. Starch reserves have been shown to decrease during cold...

The effects of stand density on the growth and microclimate of young Douglas-fir stands

Creator:: Woodruff, David R.
Abstract:: My objectives were to investigate the correlation of height and diameter growth in young Douglas-fir (Pseudotsuga menziesii) plantations with stand density, and to determine the effects of stand density on the canopy boundary layer conductance (g[subscript]ac) and microclimate characteristics of young Douglas-fir plantations. I measured annual height (h) and diameter...

Detection survey for Douglas-fir tussock moth infestations in the northern region, 1972

Creator:: Tunnock, Scott and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The last outbreak of the Douglas-fir tussock moth, Hemerocampa pseudotsugata McD., in the Northern Region subsided in 1965. Tussock moth populations were not detected again until 1970 when ornamental spruce were defoliated in Spokane, Washington, and Poison and Missoula, Montana.

Identifying candidate genes associated with cold adaptation in Douglas-fir using DNA microarrays

Creator:: Howe, Dana Kathryn
Abstract:: In forest trees from temperate and boreal regions, cold acclimation is an important adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...
