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...

Time-dependent deflection of Douglas fir beams in bending and shear modes

Creator:: Capell, Harry Thomas
Abstract:: Creep in wood has been observed since 1833 but only recently has it been studied quantitatively. The aim of this paper is to study the time-dependent deflections of Douglas fir, Coast Region beams in bending and shear modes. The general method of approach used is that of large scale observation....

Distribution of light within the crown of an open-grown Douglas-fir

Creator:: Ungs, M. J. (Michael J.)
Abstract:: A systematic investigation was made of the distribution of short wave radiation within the crown of an open-grown Douglas-fir tree. The study tree was 23 years old, 14 meters tall and had a maximum crown diameter of about ten meters. Global radiation was measured every 15 cm along eight different...

Anatomical and chemical characteristics of the Douglas-fir (Pseudotsuga menziesii (mirb.) Franko) phellem cell

Creator:: Litvay, John Dennis
Abstract:: The objectives of this study were to 1) characterize the layering in the wall of the Douglas-fir (Pseudotsuga. menziesii (Mirb. ) Franco) phellem cell, 2) determine the pitting present in this cell wall and 3) determine what compounds are present in the middle lamella of this cell. To accomplish the...

Ectomycorrhizal inoculation of Douglas-fir nursery stock with commercially produced inoculum

Creator:: Hung, Ling-ling L.
Abstract:: Nine species of ectomycorrhizal fungi were grown in liquid media over a pH range of 2-7. Species fell into five major groups: (1) growth significantly best only at the optimal pH, (2) growth increased with increase of pH, (3) significantly best growth spans three pH units, (4) spans four pH...

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...
