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...

Pollen contamination trends in a maturing Douglas-fir seed orchard

Creator:: Adams, W. T., Hipkins, Valerie D., Burczyk, J., and Randall, W. K.
Abstract:: Pollen contamination was investigated in one block (block 4) of a 10-block Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seed orchard complex in western Oregon. Blocks (25 clones each) represent different breeding zones; thus, contaminant pollen sources not only included the adjacent natural stand of Douglas-fir, but also other blocks within the...

Physiological control of fine root turnover in Douglas-fir

Creator:: Marshall, John D. (John David), 1956-
Abstract:: To determine whether shading increases drought-induced root mortality by changing the chemical composition of roots, I conducted an experiment in which high and low light treatments in combination with high and low soil moisture treatments were applied to seedlings of Douglas-fir (Pseudotsuqa menziesii Mirb. Franco). Because synthesis of suberin (a...

Diurnal and seasonal changes in xylem water potential, stomatal conductance and abscisic acid in five different habitat types of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Murphy, Ellyn Margaret
Abstract:: Sapling Douglas-fir trees on five sites in the Coastal and Cascade Mountain ranges of Oregon were measured five times during the year from the summer of 1977 through the spring of 1978 for diurnal patterns of xylem water potential, stomatal conductance and abscisic acid. Vapor pressure deficit and solar radiation...

Abscisic acid levels in relation to stomatal behavior during drought and recovery in contrasting ecotypes of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Newville, Edward G.
Abstract:: Foliage of Douglas-fir seedlings [Pseudotsuga menziesii (Mirb.) Franco] from two contrasting environments was sampled during progressive stages of two consecutive cycles of induced drought for leaf resistance, plant water potential , and abscisic acid content (ABA). One group of seedlings was placed in a controlled environment room while another group...

Distribution of light within the crown of an open-grown Douglas-fir

Creator:: Ungs, M. J. (Michael J.)
Abstract:: A systematic investigation was made of the distribution of short wave radiation within the crown of an open-grown Douglas-fir tree. The study tree was 23 years old, 14 meters tall and had a maximum crown diameter of about ten meters. Global radiation was measured every 15 cm along eight different...

Genecology of Douglas-fir from southwestern Oregon

Creator:: White, Timothy L., 1951-
Abstract:: This thesis is divided into three chapters. For all chapters, the experiments described deal with the responses of all or a subset of 72 wind-pollinated Douglas-fir families from 36 different locations in southwestern Oregon. Wind-pollinated seed was collected from each of two trees at each of the 36 locations. The...

Variation in the foliar nutrient status of several Douglas-fir provenances

Creator:: Stevens, Roderick D.
Abstract:: From a preliminary 1969 foliar analysis, eight provenances were chosen from the sixteen included in a region-wide, reciprocal Doulgas-fir provenance study for further study of variation in foliar nutrition. In the fall of 1969 separate foliar samples were collected from ten trees per provenance at each of ten plantations ranging...

Seasonal variation in leaf weight and nitrogen content of Douglas-fir plantations in the Coast Range and Cascade Mountains of western Oregon

Creator:: Smith, Robert Bruce
Abstract:: Seasonal variations in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) leaf weight and nitrogen content were measured in Oregon's Coast and western Cascade Ranges. Current and older foliage from thinned and unthinned stands were sampled monthly from October, 1978 to September, 1979. Changes in leaf weight per unit area of foliage and...

Growth and development of young Douglas-fir in relation to intra- and inter-specific competition

Creator:: Zedaker, Sheperd M.
Abstract:: This thesis explored the relationships between the growth of Douglas-fir seedlings and light and moisture resource availability as influenced by competitor type and density in the Oregon Coast Range. Twelve 360 m2 Nelder plots, encompassing a range of 300 to 15,000 cm2 per plant in 48 spokes, were established in...
