Cambial divisions in Pseudotsuga menziesii

Creator:: Sisson, Warren Elmer, Jr.
Abstract:: Mitotic activity in the vascular cambium was determined from ten samples from a single internode in each of four Douglas-fir [(Pseudotsuga menziesii (Franco.) Mirb.)]trees. Counts of interphase and mitotic nuclei from nine cores in each sample piece were averaged and expressed as the frequency and mitotic index. The sampling error...

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....

Comparative rates of CO₂ production from the forest floor in the Douglas-fir ecosystem

Creator:: Phillips, Michael John
Abstract:: To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...

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...

Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...
