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...

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,...

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...

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...

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...

Full Text:: Vikram for the degree of Master of Science in Forest Science presented on December 5, 2008. Title

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...

Creator:: Hipkins, Valerie D.
Abstract:: To help understand the mechanisms of conifer chloroplast genome evolution, we characterized the nucleotide sequences of Douglas-fir (Pseudotsuga menziesiz) and Monterey pine (Pinus radiata) chioroplast DNA that are associated with a length mutation hotspot and inversion. The chloroplast DNA ofthese two conifers are characterized by shared large inversions that are...
