The effect of harvest date and pre-storage drying methods on capsule thebaine yield, seed oil yield, and seed germination of two accessions of Papaver bracteatum Lindl.

Creator:: Seddigh, Majid
Abstract:: A field study was conducted in 1978 and 1979 at the Hyslop Crop Science Field Laboratory near Corvallis, Oregon, to determine the optimum capsule harvest date of Papaver bracteatum Lind. for thebaine yield and oil yield, while maintaining an acceptable percentage of seed germination. Accessions PI 383309 and PI 381607...

Experimental studies on species relationships in T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides

Creator:: Vieira, Luiz Gonzaga E.
Abstract:: A study of populations characteristics of T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides was completed using numerical analysis. A sample of 74 accessions of ssp. carthlicum and 20 of ssp. carthlicoides were scored for 46 characters. It was established that three morphological distinguishable groups of ssp. carthlicum can...

The effect of precipitation variation on soil moisture, soil nitrogen, nitrogen response and winter wheat yields in eastern Oregon

Creator:: Glenn, D. M. (David Michael)
Abstract:: The semi-arid regions of the Pacific Northwest are characterized by a high degree of annual temperature and precipitation variation. As a result of this climatic variation, dryland nitrogen fertilizer trials on fallow- ,wheat rotations typically demonstrate a variable response. Wheat growers in the area must not only cope with this...

Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

The population dynamics and growth of salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus)

Creator:: Maxwell, Bruce D.
Abstract:: Salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus) are clonal shrub species common to reforestation sites in the Oregon Coast Range. These species have economic importance, because they reduce conifer seedling growth and survival. A population modeling approach was used to facilitate study of the biology of these species and to...

Soil moisture storage, distribution, and use by winter wheat in a 250-350 mm precipitation zone of eastern Oregon

Creator:: Henderson, Robert L.
Abstract:: The semi-arid dryland wheat-producing areas of the Pacific Northwest are characterized by cool, moist winters and dry, hot summers. The amount of annual precipitation is generally quite variable and inadequate for annual cropping. Where soil depth is adequate, the predominant loessal soils generally supply sufficient moisture for small grain production...
