Early genetic selection for wood stiffness in juvenile Douglas-fir and western hemlock

Creator:: Urhan, Oguz S.
Abstract:: Wood modulus of elasticity (MOE), also known as wood stiffness, is one of the most important wood properties. Wood stiffness is a measure of the resistance to deflection, and is important because some products such as laminated veneer lumber, plywood, and dimension lumber require stiff and strong wood. Incorporating wood...

Variation in adaptive traits of coastal Douglas-fir : genetic and environmental components

Creator:: Balduman, Lisa M.
Abstract:: Cold hardiness and phenology are important adaptive traits for perennial plant species in temperate climates. Timing of growth, dormancy, and associated cold acclimation and deacclimation represents a delicate balance between maximizing growth under favorable conditions and minimizing frost damage under unfavorable conditions. Geographic patterns of genetic variation in adaptive traits,...

Population genetic structure of the Douglas-fir shelterwood regeneration system in southwest Oregon

Creator:: Neale, David B.
Resource Type:: Dissertation

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...

Early genetic selection in Douglas-fir : interactions with shade, drought, and stand density

Creator:: Riitters, K. H. (Kurt H.)
Abstract:: This thesis is concerned with developing techniques for identifying "superior" Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) parent trees based on seedling progeny evaluation. The growth responses of up to 14 open-pollinated families to shade, drought, and stand density were assessed in four experiments. A technique was developed to compare family height...

Range-wide patterns of allozyme variation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Li, Peng, 1961-
Abstract:: One hundred and four seed sources from throughout the range of Douglas-fir (Pseudotecia menzieaii (Plirb.) Franco) were analysed at 20 enzyme loci to determine patterns of genetic variation and to examine intraspecific phylogeny. On average the seed sources were polymorphic at 37 percent of the loci (range 5.0-65.0), with mean...

Genetic variation in shoot-growth patterns of Douglas-fir populations from southwest Oregon

Creator:: Kaya, Zeki
Abstract:: This study had three objectives: (1) to teat the hypothesis that multiple flushing of the terminal shoot (intermittent growth pattern) in Douglas-fir seedlings (Pseudotsuca menziesii var. menziesii) has an adaptive significance, especially in inland populations from the drier regions in southwest Oregon; (2) to evaluate the genetic and adaptive consequences...

Genetic diversity and differentiation in Douglas-fir from RAPD markers of nuclear and mitochondrial origin

Creator:: Aagaard, Jan Erik
Abstract:: In order to better understand the evolutionary patterns revealed by molecular markers, we studied genetic diversity and differentiation of populations and races of Douglas-fir using randomly amplified polymorphic DNA (RAPD) markers of nuclear and mitochondrial origin. We conducted a range-wide survey of RAPD diversity and differentiation, and compared RAPDs and...

Stiffness of Douglas-fir lumber : effects of wood properties and genetics

Creator:: Vikram, Vikas
Abstract:: Wood stiffness is one of the most important properties of lumber and veneer. We studied wood stiffness (modulus of elasticity, MOE), wood density, microfibril angle, and knots in a 25 year-old wind pollinated progeny test (50 families, ~ 373 trees) of coastal Douglas-fir to understand the potential for genetically improving...

Patterns of genetic variation within and among breeding zones of Douglas-fir in southwest Oregon

Creator:: Loopstra, Carol Anne
Abstract:: Three hundred fifty families from 11 breeding zones in southwest Oregon were grown in a common garden in Corvallis, Oregon, and patterns of genetic variation for seed weight and six first-year seedling characteristics were described. For most characteristics, large differences among breeding zones were found along an east-west transect, with...
