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...

The physiology of plagiotropic growth of rooted cuttings of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco]

Creator:: Starbuck, Christopher J.
Abstract:: Experiments were conducted to determine if the plagiotropic growth habit of rooted cuttings of Douglas-fir might result from a system favoring the accumulation of indoleacetic acid in the adaxial side of the shoot in response to vertical placement. Actively growing excised branch terminals were subjected to gravitational disorientation to determine...

The effects of supercritical CO₂ on the bending properties and treatment defects of four refractory wood species

Creator:: Anderson, Matthew E.
Abstract:: It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood species may be an attractive alternative to conventional liquid carriers. While SCF impregnation has many potential advantages, some wood species...

The effect of osmotic moisture stress during germination on Douglas-fir (Pseudotsuga menziesii)

Creator:: Stewart, Ronald E
Abstract:: Commercially collected Douglas-fir seed from a moist coastal ecotype (LaPush, Washington) and a dry inland ecotype (Kaibab National Forest, Arizona) were subjected to osmotic stresses ranging from 0 to -8 atmospheres using Carbowax polyethylene glycol 6000 during imbibition and germination. To determine the effect of osmotic stress on the initiation...

The economic feasibility of preheating Douglas-fir blocks prior to peeling

Creator:: Baskin, Richard
Abstract:: Past research and industrial sources have implied that preheating Douglas-fir Pseudotsuga menziesii (Mirb.) Franco prior to peeling veneer was economically feasible. To test this, the effect of treatment temperature on veneer yield and thickness variation for three diameter classes of low grade Douglas-fir logs was studied and related to the...

Starch content and crown growth in two Douglas-fir stands

Creator:: Kilpatrick, Kran James
Abstract:: The objectives of this investigation were to measure the seasonal and diurnal variations of starch as well as to relate these variations to growth of the trees. This study also microscopically examined the needles to determine if starch exists in granular form in Douglas-fir. The objectives were designed to gain...

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...
