The role of soil-water depletion and plant-moisture stress in soil classification and cambial activity of Douglas-fir

Creator:: Thomas, Byron R.
Abstract:: Relationships between soil-water stress and plant-moisture stress were studied with respect to soil classification and cambial activity in Douglas-fir. The study sites were forested with Douglas-fir and located in McDonald Forest and near Marys Peak in the Oregon Coast Range. Soil-water depletion was followed by the use of gypsum blocks...

Silvicultural impacts of sheep grazing in Oregon's Coast Range

Creator:: Leininger, Wayne C.
Abstract:: A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...

Root initiation and elongation in Douglas-fir, Pseudotsuga menziesii (Mirb.) franco, stem cuttings as related to bud and cambial activity

Creator:: Bhella, Harbans Singh
Abstract:: The relation of bud and cambial activity to root initiation and elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stem cuttings was studied through two successive growth cycles. Stem cuttings of current season's growth were taken periodically from field-grown Douglas-fir trees to determine: (1) origin and development of root initials; and...

Comparison of Phellinus weirdi root rot damage in a 60-year-old Douglas-fir (Pseudotsuga menziesii) stand with the damage in the preceding old-growth stand

Creator:: Tkacz, Borys M.
Abstract:: Laminated root rot of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) caused by the fungus Phellinus weirii (Murr.)Gilbertson was studied in two successive stands in the Oregon Coast Range. Damage due to the disease in a 60-year-old second-growth stand was compared with incidence in the preceding 300-year-old stand on the same site....

Factors affecting inter-tree root contact and the transmission of Phellinus weirii in young-growth Douglas-fir

Creator:: Reynolds, Keith M.
Abstract:: Groups of second-growth Douglas-fir (Mirb.) Franco were excavated in plots of two to six trees on two sites in the vicinity of Cowichan Lake, Vancouver Is., British Columbia. Eleven excavation plots provided 36 trees which could be studied in pairs (a total of 50 pairs) in order to ascertain the...

Fungi associated with Douglas-fir seed during cone development, seed processing, and storage

Creator:: Gordon, Lewin Roland
Abstract:: The Pacific Coast form of Douglas-fir in natural forest succession is an intermediate species thriving in the Coast Range and Cascade Mountains of the Pacific Northwest. This species constitutes 26 percent of the standing timber in the United States, and 24 percent of the nation's annual timber harvest. Characteristics of...

Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

Root initiation and differentiation in Pseudotsuga menziesii (Mirbel) Franco

Creator:: Bogar, Gerald Dale
Abstract:: Tissue differentiation of the primary root and its associated laterals is reported. Secretory elements are the first of the primary tissues to mature. They appear to be located between the precursory phloem and pericycle in the primary root, but are more closely associated with the pericycle in long lateral roots....
