Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

Creator:: Pruyn, Michele L., Gartner, Barbara L., and Harmon, Mark E.
Abstract:: • A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...

Stability and density management in Douglas-fir plantations

Creator:: Hann, David W.
Abstract:: In their recent Canadian Journal of Forest Research Comment 368 article, Wilson and Oliver (2000) developed an equation for predicting the average ratio of height to diameter at breast height for the largest 250 trees/ha (H/DL250) in unthinned stands as a function of initial density and dominant height of the...

Micropropagation of Douglas fir (Pseudotsuga menziesii) in a double-phase culture medium

Creator:: Gross, Leah M.
Abstract:: The timber and Christmas tree industries are important components of the Pacific Northwest economy. A goal of both industries is to produce high quality trees with high growth rates. Accomplishing this requires increased genetic quality of the trees grown. Tissue culture provides the most promise for propagating these superior genotypes....

Influence of root architectural development on Douglas-fir seedling morphology and physiology

Creator:: Jacobs, Douglass Frederick
Abstract:: A series of experiments were established to gain a better understanding of the extent to which Douglas-fir seeding root architecture may be manipulated and subsequent influences on seedling morphological and physiological development. The incorporation of amendments into nursery soils changed root architecture to some degree, but did not produce large...

Effects of vegetation control, stock size, fertilization, and soil moisture on the shoot and root development of Douglas-fir seedlings

Creator:: Burney, Owen T.
Abstract:: The overall purpose of this study was to examine the root and shoot development of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings at two distinct time periods in seedling establishment (after I and 3 growing seasons) in response to fertilizer, stock size, vegetation control, and soil moisture treatments. Two separate experiments...

Genetic variation in drought hardiness of coastal Douglas-fir seedlings from British Columbia

Creator:: Anekonda, T. S., Lomas, M. Christine, Adams, W. T., Kavanagh, Kathleen L., 1955-, and Aitken, S. N.
Abstract:: Abstract: Genetic variation in drought hardiness traits and their genetic correlations with growth potential and17re1c6overy traits were investigated in 39 full-sib families of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) from southwestern British Columbia. Seedlings of these families were grown in raised nursery beds and subjected to three moisture...

Douglas-fir hydraulic architecture and relationships among xylem properties at multiple scales via a Bayesian analysis

Creator:: Dunham, Sonya M.
Abstract:: This study investigated variation in xylem anatomy, hydraulic properties, and the relationship between anatomy and properties within Douglas-fir trees at multiple scales. The hierarchical scales in the study included fertilization treatments (fertilized and unfertilized), trees within the treatments, and positions within the trees. Tracheid diameter, tracheid length, percent latewood, number...

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...

Development and application of SSR markers for measuring gene flow in Douglas-fir

Creator:: Slavov, Gancho Trifonov
Abstract:: Gene flow is a major evolutionary force and an important factor in the breeding and conservation of forest trees. I studied the applicability of SSR markers for measuring pollen-mediated gene flow (i.e., pollen flow) in Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco). I developed SSR markers, tested alternative approaches for measuring pollen...

Effect of soil type, fertilizer, and soil moisture on 1+0 Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings

Creator:: Arellano Ogaz, Eduardo
Abstract:: Soil physical, chemical, and biological components as well as climate and physiographic characteristics can interact to have a great effect on forest regeneration and seedling growth response to different establishment activities. The objective of this project was to increase the understanding of the interactions between soil type, controlled-release fertilizers, and...
