Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Watershed response to western juniper control

Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

Use of livestock to improve the quality of elk winter range forage in northeastern Oregon

Creator:: Clark, Patrick Eugene
Abstract:: The effects of late spring defoliation on the winter forage quality of bluebunch wheatgrass (Agropyron spicatum [Pursh] Scribn. & Smith), Idaho fescue (Festuca idahoensis Elmer) and elk sedge (Carex geyeri Boott) and the response of wintering Rocky Mountain elk (Cervus elaphus nelsoni Bailey) to changes in winter range forage quality...

The effects of soaking and low temperatures on germination and seedling vigor of snap beans (Phaseolus vulgaris L. cv. Slenderette)

Creator:: Walls, Timothy W.
Resource Type:: Masters Thesis

Temporal and spatial variability of methane emissions from Alaskan Arctic tundra

Creator:: Morrissey, L. A.
Abstract:: Methane flux was measured from northern Alaska Arctic Coastal Plain wetlands to assess the spatial and temporal variability of Arctic tundra emissions during the summers of 1987 through 1990. Initially, the role of vegetation in the release of methane from substrate to atmosphere was assessed. Methane emissions were shown to...

Selected factors affecting the pattern of agricultural land conversion in Washington County, Oregon, 1963-1973

Creator:: Furuseth, Owen J., 1949-
Abstract:: In recent years the conversion of agricultural lands to more intensive non-rural land uses has become a focus of increasing public awareness and concern. The growing attention to farmland conversion is manifested in increasing public policies and legilsation to protect agricultural and forestry land uses. Nevertheless, our understanding of the...

Schedule-based material requirements planning : an artificial intelligence approach

Creator:: Kim, Sunuk
Abstract:: The objective of this research project was to identify the limitations associated with schedule-based Material Requirements Planning (SBMRP) and to present a knowledge-based expert system (KBES) approach to solve these problems. In SBMRP, the basic strategy is to use backward or forward scheduling based on an arbitrary dispatching rule, such...

Responses of males to a pheromone blend of female Oriental fruit moth with and without E8, E10-dodecadien-1-ol, a pheromone component of codling moth (Lepidoptera: Tortricidae)

Creator:: Allred, Darin B.
Abstract:: E8,E10-dodecadien-1-ol, the primary component of the female sex pheromone of codling moth, Cydia pomonella L., has no attraction to male Oriental fruit moth (OFM), C. molesta (Busck). However, this compound when added to the OFM pheromone blend of Z8-dodecenyl acetate (85.5%), E8-dodecenyl acetate (5.5%), and Z8- dodecen -1 -ol (9.0%),...
