Genetics of fall, winter and spring cold hardiness in coastal Douglas-fir seedlings

Creator:: O'Neill, Gregory Arthur, 1961-
Resource Type:: Dissertation

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...

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...

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...

The influence of stand structure and topography on growth, leaf area and efficiency of young Douglas-fir in the Oregon Coast Range

Creator:: Kaiser, Elisabeth H.
Abstract:: The relative influences of stand structure and topographic variation on volume growth, photosynthetic surface area, and stem growth efficiency were determined for six 17 to 23 year old well stocked stands in the central Oregon Coast Range. Plots were assigned to topographic classes (aspect, slope steepness, and slope position), by...

Pruning young Douglas-fir (Pseudotsuga menziesii [mirb.] Franco) in a western Oregon agroforestry setting : changes in tree water relations and effects on forage production

Creator:: Withrow-Robinson, Bradford A.
Abstract:: There is renewed interest in agroforestry as a management strategy for marginal agricultural lands in western Oregon. Silvopastoral systems combine tree and forage production, which involve crops and practices familiar to the area. The objective of this study was to determine how management influences the physiology and ecological interactions of...

The characteristics and dynamics of snags in Douglas-fir forests of the Oregon Coast Range

Creator:: Cline, Steven Paul
Abstract:: Snags, standing dead trees, are used by many species of wildlife. Despite the importance of snags their basic ecology remains unknown. Some forest management practices eliminate snags from the forest with a concomitant effect upon snag-dependent wildlife. My objective was to describe the density, spatial distribution, and physical character of...

Some guidelines for planting 2-0 Douglas-fir in Oregon : a preliminary report

Creator:: Zaerr, Joe B., Lavender, Denis P., and Oregon State University. Forest Research Laboratory
Abstract:: The Dwight L. Phipps State Forest Nursery at Elkton annually supplies 22 million 2-0 Douglas-fir seedlings to Oregon land managers. Some managers report excellent success in planting, but others report failures, particularly when planting late in the season. In some instances poor survival seemed to be related to storage. Physiological...

Examining bias in estimating the response variable and assessing the effect of using alternative plot designs to measure predictor variables in diameter growth modeling

Creator:: Zumrawi, Abdel Azim M. A.
Abstract:: Diameter growth of Douglas-fir (Pseudotsuqa menziesii (Mirb.) Franco) estimated from increment cores was compared with that obtained from repeated measurements of tree diameter on permanent plots located in two Douglas-fir study areas in the central Coast Range of Oregon. Growth was measured for a 6-year period (1979- 1985). Diameter growth...
