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....

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...

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...

A study of several anatomical variables in relation to their effect on tensile strength of Douglas-fir

Creator:: McMinimy, Lawrence Otto
Abstract:: A microscopic study was conducted on specific gravity wafers taken from standard tensile strength specimens of young growth Douglas-fir. Samples were studied to determine the effect of variables such as percent summerwood, fiber length and fibril angle on tensile strength of Douglas-fir. The sample specimens were picked so effects of...
