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....

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...

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...
