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...

The effects of inbreeding and supplemental mass pollination upon seed yields in a Douglas-fir seedling seed orchard

Creator:: Cress, Daniel W.
Abstract:: Effects of four inbreeding levels (F = 0, 0.125, 0.25, 0.5) and two supplemental mass pollination (SMP) methods (agitation of naturally shedding pollen with "air blaster" and pollen application from large "pollen wand" atomizer) were evaluated on seed of trees from eleven full-sibling Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) families in...

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...

Impact of insects on seed production in a Douglas-fir seed orchard in Oregon

Creator:: Dombrosky, Scott A.
Abstract:: The impact of various factors on seed production in a Douglas-fir (Pseudotsuga menziesii) seed orchard in western Oregon was examined by monitoring the fate of seeds in thirty cones, stratified into three crown levels, on each of ten trees during the 1984 growing season. Cones were examined monthly between April...

Genetic variation in Douglas-fir : a 20-year test of provenances in eastern Nebraska

Creator:: Van Haverbeke, David F., 1928-
Abstract:: Twenty-year-old Douglas-fir trees in provenances from Arizona, New Mexico, and southern Colorado survived better and grew taller; but incurred more winter injury in eastern Nebraska than trees from provenances from northern Colorado, southern and western Montana, northern Idaho, Canada, and eastern Washington. However, surviving trees from Pacific Coast, and northern...

Physiological and biochemical studies of stratified Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seeds after redrying, storage, and subsequent germination

Creator:: Malavasi, Marlene de Matos
Abstract:: The physiological and biochemical responses of Douglas-fir seeds to stratification, redrying, storage and subsequent germination were determined. Stratification increased seed vigor, embryo and gametophyte phosphorylative efficiency and RNA synthetic ability. Redrying seems to increase the rate of enthryonic nucleic acid synthesis, speed of germination and seedling vigor. ATP, total adenosine...

Spot seeding Douglas-fir in the Pacific Northwest using a Finnish shelter seeding method

Creator:: Wolff, Scott
Abstract:: One of the largest problems facing the forester in the Pacific Northwest today is the economical, rapid rehabilitation of cut-over lands. Many of these cut-over lands are planted to Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco]. Previously, both aerial and spot seeding techniques have been evaluated for their efficiency in Douglas-fir regeneration....

Evaluating radial compression, color indicator and micro-toughness tests to detect early decay in Douglas-fir

Creator:: Smith, Susan M.
Abstract:: Three methods--radial compression strength, color indicators of decay and micro-toughness, an examination of tracheid fracture patterns, were evaluated for detection of early decay and for application to field use. Three-eighth-inch diameter plugs 3/4-inch long, cut from the sapwood and heartwood of a Douglas-fir pole free of decay, were decayed by...

Microdistribution and retention of chloropicrin in wood

Creator:: Goodell, Barry Scott
Abstract:: Quantitative and qualitative information on the retention of chlorinated residues in chloropicrin treated wood is lacking. Retention of chloropicrin and its chemical breakdown products in wood, and the effects of chloropicrin treatment of wood on invading decay fungi are explored in this thesis. Chlorinated residues in amounts up to 1.5%...
