Polyphenols of red alder : chemistry of the staining phenomenon

Creator:: Karchesy, Joseph
Resource Type:: Dissertation

Effects of thermoperiod on the early growth of red alder from different elevations and geographic sources

Creator:: Campbell, Allan, 1936-
Abstract:: This study was designed to help elucidate what differences, if any, exist within the species Alnus rubra Bong., grown naturally at various elevations and locations throughout the Pacific Northwest and coastal Alaska. Increasing importance of the species, including both economic and silviculture values, prompted the investigation into the early growth...

Effects of density stress and soil productivity on size, mortality and nitrogen fixation in artificial populations of seedling red alder (Alnus rubra Bong.)

Creator:: Smith, Nicholas J.
Abstract:: Red alder (Alnus rubra Bong.) seedlings were grown at three initial spacings (8 x 8 cm, 4 x 4 cm, and 2 x 2 cm) and on two soil types (forest soil and river loam) under greenhouse and lath house conditions for 525 growing days. There were seven harvest dates,...

Inoculation potential of soil-borne Frankia on red alder (Alnus rubra Bong.)

Creator:: Martin, Kendall J.
Abstract:: Inoculation trials were set up in fumigated nursery beds for red alder (Alnus rubra Bong.) seedling production. Frankia inoculum was applied in eight treatments: control, nodule suspension, and three levels of cell suspension (strain ArI5) applied with and without a peat carrier. Seedlings were evaluated at midseason and lifting. The...

Nitrogen dynamics in red alder

Creator:: Swanston, Christopher W.
Abstract:: Red alder (Alnus rubra Bong.) is recognized as an important source of nitrogen to ecosystems that it inhabits. I examined N dynamics within alder trees, alder leaf litter, and the soil beneath alder leaf litter. ¹⁵Nitrogen, a stable isotope of N, was used as a tracer to follow the movement...

Water stress, fertilization and light effects on the growth of nodulated, mycorrhizal red alder seedlings

Creator:: Koo, Chang Duck
Abstract:: Red alder (Alnus rubra Bong.) seedlings fertilized with NH4NO3 or inoculated with a pure culture Fran/cia and inoculated with live or dead spores of the mycoirhizal fungus Alpova diplophloeus (Zeller & Dodge) Trappe & Smith were grown in a growth chamber or in a greenhouse for six months Frankia inoculation...

Influence of soil and rhizosphere actinomycetes on Frankia infection and nitrogenase activity in Alnus rubra Bong

Creator:: Rojas-Melo, Nestor S.
Abstract:: Nodulated roots of young red alder trees and soil samples were collected from a 5 year old clearcut on Mary's Peak, Oregon. Frankia was isolated from root nodules, andactinomycetes from nodules, roots, and soil. A total of 229 pure culture actinomycete isolates were recovered: 131 colonies from root surfaces, 52...

Seasonal and diurnal trends of leaf water potential and stomatal conductance of red alder (Alnus rubra Bong) growing along a density gradient in western Oregon

Creator:: Lu, Shengjun
Abstract:: Three Nelder plots of 3-year-old red alder (Alnus rubra Bong) were used for this study at the Cascade Head Experimental Forest, Oregon in the growing season of 1988 at an elevation of 330 meters. Each Nelder plot represented a range of densities from 238 to 101,219 trees per hectare. The...

Seasonal estimates of nitrogen fixation by Alnus rubra and Ceanothus species in western Oregon forest ecosystems

Creator:: Kim, Dong Yeob
Abstract:: Two case studies of 5 ecosystems were used to examine the nitrogen fixation rate of red alder (Alnus rubra Bong.), varnishleaf (Ceanothus velutinus var. laevigatus (Hook.) T. & G.), deerbrush (C. i ntegerrimus H. & A.), and snowbrush (C. velutinus var. velutinus Dougl. Ex Hook). The first case study assayed...
