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...

Identification and development of cultural practices for upland rice production systems for savanna soils of Colombia

Creator:: Leal-M, Dario
Abstract:: A great potential for increasing upland rice production exists in the savanna soils of Colombia. These vast areas are currently underutilized. However, they have good soil structure, flat topography, coupled with sufficient and well distributed rainfall, making savanna soils ideal for upland rice cropping system. The major constraints to upland...

Response of grain yield, plant height and kernel weight in three winter wheat crosses (Triticum aestivum, L. em Thell) to different methods of selection

Creator:: Salmeron-Zamora, Jose Juan
Abstract:: This study was undertaken to see if a method of handling segregating populations could be employed which combined the positive attributes of the traditional pedigree and-bulk methods. Derived F₅ lines from the pedigree, bulk, and what is identified as a modified bulk method, were obtained from three winter wheat crosses....

Apple mycorrhizae and their effects on growth and nutrient concentration in apple seedlings grown in two soils with varied levels of P

Creator:: Geddeda, Yosef Ibrahim
Abstract:: A study was conducted to characterize the vesicular-arbuscular (VA) fungi of apples grown in Oregon. Using roots and soil from apple orchards as inoculae, six different fungal species were found in pot cultures: Gigaspora margarita Becker and Hall, Glomus fasciculatum (Thaxter sensu Gerdemann) Gerd. and Trappe, Glomus mosseae (Nicol. and...

A map enhancement for terrain visualization under Night Vision Goggle compatible lighting systems

Creator:: Thompson, Wiley C.
Abstract:: For the Army aviator, Night Vision Goggle (NVG) flight in the tactical rotarywing profile is a very demanding, task saturated environment. Map navigation is just one of the many tasks that must be accomplished during flight. The dim, monochromatic lighting required for NVG flight alters map colors, decreases image detail...

Monitoring sand dune processes at the Oregon Dunes National Recreation Area : can pre-vegetated conditions be restored?

Creator:: Mitteager, Wendy Ann
Abstract:: The Oregon Dunes National Recreation Area is managed by the Siuslaw Forest division of the United States Forest Service (USFS). This area has gradually been overcome by vegetation since the 1950's, originating with the exotic European Beach Grass (Ammophila arenaria). The invasion of this exotic vegetation has resulted in a...

Assessment of impacts of Canada geese on wheat production

Creator:: Louhaichi, Mounir
Abstract:: Numbers of wild Canada geese (Branta canadensis) have increased dramatically during the past 30 years in the lower Columbia and Willamette Valley systems. The damage they cause by grazing and trampling plants can be substantial. The objectives of this research were to: 1) Develop methods that provide reliable estimates of...

Using Data Loss and Duplication Maps to study data use associated with nearest-neighbor resampling

Creator:: Perigny, Mathew
Abstract:: Nearest-neighbor resampling is a common procedure used by cartographers to reproject raster data sets. This type of resampling is useful because it retains the data from the original raster data set. However, during nearest-neighbor resampling some of the original data will be lost as it is reprojected, while other data...
