Influence of light on the growth of advance regeneration in the understory of Douglas-fir dominated forests in western Oregon

Creator:: Deisenhofer, Florian
Abstract:: The growth potential of Douglas-fir, grand fir and western hemlock advance regeneration in the forest understory of Douglas-fir-dominated forests was investigated to detennine the feasibility of selection cutting systems in northwest Oregon. This study compared the growth of Douglas-fir, grand fir and western hemlock advance regeneration along a light gradient...

The effect of plant moisture stress on the physiology and establishment of planted Douglas-fir and ponderosa pine seedlings

Creator:: Cleary, Brian D.
Abstract:: The role of moisture stress in seedling physiology and establishment was studied in both the field environment and laboratory experiments. Plant moisture stress was measured using the pressure chamber technique. This technique was modified and tested using a fascicle of pine needles as a sample, an improvement which allows the...

The effects of low temperatures on dormancy release in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) from western Oregon, Washington, and California

Creator:: Sugano, Albert Itsuki
Abstract:: The effect of low temperatures given at different times and duration upon the time of bud burst, shoot elongation, number of needles developed and needle length in Douglas-fir plants from the Oregon Cascades and three coastal areas ranging from Washington to California were determined. The plants were grown outside in...

Survival and some physiological aspects of tissue cultured cells from Douglas-fir (Pseudotsuga menziesii Mirb. (Franco)) and a poplar hybrid after freezing to liquid nitrogen temperature

Creator:: Binder, Wolfgang Dieter
Abstract:: Cell aggregate size in both Douglas-fir and poplar suspension cultures was reduced by the addition of the chelator compounds EDTA and CDTA at concentrations under 100 ppm. Reduced cell aggregate size increased growth efficiency of suspension cultures of both species. Cell aggregates 550 j.z. or smaller in size were used...

Effects of water stress on phenology, physiology, and morphology of containerized Douglas-fir (Psuedotsuga menziesii (mirb.) Franco) seedlings

Creator:: Khan, Shafiqur Rehman
Abstract:: Approximately 3-4 month-old containerized Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings (seed zone 262 and 271) were subjected to 6 moisture stress treatments (65, 53, 41, 29, 17 and 7% soil water content by volume of dry soil) starting July 4 to September 22, 1991 at Forest Research Laboratory's greenhouse at...
