Survival and growth of Douglas-fir seed sources in the Hospital Tract rangewide source archive plantation

Creator:: Gamble, William E., Adams, W. T., Tappeiner, J. C. (John C.), and Oregon State University. Forest Research Laboratory
Abstract:: "In 1954, Dr. Helge Irgens-Moller initiated a rangewide collection of seed and seedlings of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Nearly 700 trees or stands were sampled in 10 western states, Canada, and Mexico. From 1957 to 1971, 639 of these collections were planted in the Hospital Tract Rangewide Source Archive...

Full Text:: that much of the genetic variation on a geographical scale in Douglas-fir is the result of adaptation

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...

Physiology and genetics of drought hardiness in coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) seedlings

Creator:: Lomas, M. Christine
Abstract:: Physiology and genetics of drought hardiness were investigated in two-year-old coastal Douglas-fir seedlings from 39 full-sib families obtained from coastal British Columbia and grown at Oregon State University, Corvallis, Oregon. The seedlings were subjected to three drought treatments (control, moderate, and severe drought) in their second growing season (June through...

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

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

Quantitative genetic structure of Douglas-fir populations from southwest Oregon

Creator:: Hamlin, James
Abstract:: The major objectives of this study were: (1) to determine the extent to which southwest Oregon populations of Douglas-fir [Pseudotsuga menziesii var menziesii (Mirb.) Franco) differ in quantitative genetic structure (QGS); (2) to determine whether differences in QGS are associated with the environments from which populations originate; and (3) to...

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,...

Genetic variation and phenotypic stability among three elevational sources of coastal Douglas-fir from southwest Oregon

Creator:: Mangold, Robert
Abstract:: This study had three objectives: (1) to determine the degree to which within-source genetic variation and genetic correlations differ among elevational sources of Douglas-fir [Pseudotsuga menziesii (Mirb). Franco var. menziesii]; (2) to ascertain the degree to which phenotypic stability differs among and within elevational sources; and (3) to compare the...

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...
