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

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

Genetic variation of wood density components in coastal Douglas- fir and their relationships to growth rhythm

Creator:: Vargas-Hernandez, Jesus
Abstract:: Overall wood density is a complex trait resulting from the interaction of three components: average earlywood density, average latewood density, and latewood proportion. In order to better understand the genetic control of wood density in juvenile Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and to assess the utility of information on its...

Effects of seed characters and competitive environment on two-year performance of open-pollinated Douglas-fir families

Creator:: St. Clair, John Bradley
Abstract:: Ungerminated seed and recent germinants from 39 open-pollinated Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) families were planted in each of three competitive environments in order to determine the degree to which growth differences among families are influenced by competitive environment, seed weight, and date of emergence. The three competitive...

Response of annual growth ring components to soil moisture deficit in young plantation grown Douglas-fir in coastal British Columbia

Creator:: Bower, Andrew David
Abstract:: The goal of this study was to determine whether annual growth ring variables of young coastal Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) growing in progeny tests are sensitive to availability of soil moisture during the growing season. If ring variables are found to respond to soil moisture deficit (SMD)...

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

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

The influence of distance and floral phenology on pollen gene flow and mating system patterns in a coastal Douglas-fir seed orchard

Creator:: Erickson, Vicky J., 1955-
Resource Type:: Masters Thesis

Seed set and the proportion of progeny due to self-fertilization in a Douglas-fir seed orchard

Creator:: Omi, Steven Katsu
Abstract:: The effects of clonal variability, crown position of cones, and top-pruning of ramets to reduce height growth, on 1) the proportion of viable self-fertilized progeny (s) and 2) the proportion of filled seeds (PF), were investigated in a 20 year-old Douglas-fir (Pseudotsuga menziesii [Mirb.1 Franco) seed orchard. Cones were collected...

Early testing of Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) for Swiss needle cast tolerance

Creator:: Temel, Fatih
Abstract:: The relationship between the level of Phaeocryptopus gaeumannii (Rohde) Petrak colonization and severity of Swiss needle cast (SNC) symptoms, the possibility of early testing of Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco) for SNC tolerance, and geographic variation in coastal Oregon with respect to SNC tolerance were investigated. Comparisons between...

Genetic variation in phenology of bud and cambial activity in coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco)

Creator:: Li, Peng, 1961-
Abstract:: Growth phenology (i.e., timing of growth initiation and cessation) is important to adaptation. This study examined the extent of genetic control of bud and cambial phenology and their relationships with stem growth in pole-size Douglas-fir (ages 13 to 16 years) from 60 open-pollinated families. The availability of bud phenology data...

Multi-trait selection in coastal Douglas-fir

Creator:: Aubry, Carol A.
Abstract:: Index selection provides an efficient means of conducting selection on multiple traits by combining information on economic value, heritability, and the genetic and phenotypic correlations between traits to improve overall merit. The use of this method in forestry has been hampered by the lack of knowledge of the relative importance...
