Agronomic potential and physiological performance of synthetic hexaploid wheat-derived populations

Creator:

del Blanco, Isabel Alicia

Resource Type:

Dissertation
Estimated plant water use and crop coefficients for drip-irrigated hybrid polars

Creator:

Gochis, David J.

Abstract:

Estimations of plant water use can provide great assistance to growers, irrigators, engineers and water resource planners. This is especially true concerning the introduction of a new crop into irrigated agriculture. Growing hybrid poplar trees for wood chip stock and veneer production under agronomic practices is currently being explored as...

Masters Thesis
Water management effects on birdsfoot trefoil seed production

Creator:

García-Díaz, Carlos Alberto

Abstract:

There is no information available on water management of birdsfoot trefoil grown for seed. Information is also not available describing how to minimize seed losses due to shattering in order to obtain consistently high birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify crop water use,...

Expression and inheritance of tolerance to waterlogging stresses in wheat (Triticum aestivum L.)

Creator:

Boru, Getachew

Resource Type:

Dissertation
Meta-sedimentary bedrock as an alternative source of water for forest ecosystems in a Mediterranean climate

Creator:

Zwieniecki, Maciej A.

Abstract:

Evaluation of meta-sedimentary bedrock as a source of stored water available to plants in a mediterranean climate is presented based on: root length distribution (RLD), root morphology, rock water holding capacity and seasonal pattern of water depletion. Studies were performed in southwestern Oregon under young stands of whiteleaf manzanita, ponderosa...

Resource Type:

Dissertation
Evaluating methods for measuring soil-CO₂-efflux in artificial, controlled and natural ecosystems

Creator:

Nay, Stephan Mark

Resource Type:

Masters Thesis
Evaluation of allelopathy as a mechanism by which buckwheat suppresses Canada thistle and its mycorrhizae

Creator:

Eskelsen, Steven R.

Abstract:

Experiments were conducted to determine if allelopathy is a mechanism by which buckwheat interferes with a) the growth of Canada thistle and/or b) mycorrhizae colonization in Canada thistle roots. In a competition experiment, buckwheat plant biomass was only affected by the intraspecific competition from other buckwheat plants and not by...

Dissertation
Transformations of sulfur in wetland rice soils

Creator:

Islam, M. Mujibul

Resource Type:

Dissertation
Dynamic finite element analysis of micropolar elastic materials

Creator:

Kim, Jong-bum, 1960-

Abstract:

In granular or fibrous materials, in which the dimensions of the internal structure can be of the same order of magnitude as major flaws or holes, classical elasticity theory does not consistently provide accurate models of the large stress gradients that may develop. With the incorporation of additional rotational degrees...

Resource Type:

Dissertation
Effects of microsite alteration on soil climate, nitrogen mineralization, and establishment of Picea Glauca x Engelmannii seedlings in the sub-boreal spruce zone of west-central British Columbia

Creator:

Macadam, Anne M.

Abstract:

Site preparation treatments are often used prior to the planting of clearcut forest lands to improve planter access and to increase the number and quality of planting spots. Most mechanical site preparation treatments alter the configuration and material composition of surface soil materials, and can have marked effects on soil...
