Physiological control of fine root turnover in Douglas-fir

Creator:: Marshall, John D. (John David), 1956-
Abstract:: To determine whether shading increases drought-induced root mortality by changing the chemical composition of roots, I conducted an experiment in which high and low light treatments in combination with high and low soil moisture treatments were applied to seedlings of Douglas-fir (Pseudotsuqa menziesii Mirb. Franco). Because synthesis of suberin (a...

Carbon and nitrogen allocation patterns of 2-0 Douglas-fir seedlings following nitrogen fertilization in the autumn

Creator:: Margolis, Hank A.
Abstract:: Douglas-fir (Pseudotsuga menziesii Mirb. Franco) seedlings at a nursery in western Oregon were fertilized with nitrogen in October. Free amino acid (FAA) and total nitrogen concentrations in needles, stems and fine roots were followed from before fertilization until just prior to budbreak the following spring. Before budbreak in mid-March, the...

Soil and growth studies in Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stands near Molalla, Oregon

Creator:: Strand, Robert Fenton
Abstract:: In 1957 three Douglas-fir stands (15-, 25-, and 40-year-old age classes) were selected on a tree farm in the Cascade foothills of northwestern Oregon to study factors affecting site productivity. Soil-moisture, soil-temperature and seasonal radial- growth pattern measurements were made with a Colman moisture meter and a dial gauge dendrometer...

Physiological responses of four Douglas-fir populations in three contrasting field environments

Creator:: Emmingham, William H.
Abstract:: When trees from 16 populations of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco. var. menziesii) were grown at ten geographically diverse locations for seven years, those from a Vancouver Island source were among the top three for height growth on nine of the ten plantations (Rowe and Ching, 1974). In contrast, growth...

Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

Creator:: Pruyn, Michele L., Gartner, Barbara L., and Harmon, Mark E.
Abstract:: • A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...

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...
