Taxonomy of desert truffles : the genera Phaeangium and Tirmania

Creator:: Alsheikh, Abdulmagid M.
Abstract:: Mycorrhizal fungi are important in food production of arid lands. The desert truffles not only form a symbiotic association with range plants but also form fruiting bodies which are both prized as food and nutritious. The taxonomy and ecology of two genera of desert truffles are treated in this thesis....

Evaluation of germination responses and early seedling development of selected medicago and hedysarum species

Creator:: Jabbes, Mohamed
Abstract:: Germination strategies and early seedling development of selected Medicago and Hedysarum species were evaluated to identify plants with high potential for range rehabilitation in central Tunisia. Temperature (5°C to 25°C) and water stress (0 MPa to -0.8 MPa) affected the germination percentage of all Medicago and Hedysarum species. Water stress...

Evaluation of native and introduced plant species for revegetating Central Tunisian rangelands

Creator:: Chouki, Salah
Abstract:: The evaluations performed in this thesis were intended to provide a partial basis for the selection of species and varieties for reseeding Central Tunisian rangelands. The first evaluation determined the effects of four moisture regimes and two growth mediums on seedling emergence and early root and shoot development of eight...

Evaluation of Rhizobium strains with three Mediterranean forage legumes for biological nitrogen fixation

Creator:: Streeter, Donald J.
Abstract:: Centuries of continuous grain cropping in northern Africa have reduced N levels in soils to a degree such that agricultural production is now largely dependent upon nitrogen fertilizer. Through the identification of highly effective legume and Rhizobium strain combinations, the production of protein-rich livestock forage and green manure can be...

Insect pests of economic importance on cereal crops in the Senegal River Basin, West Africa

Creator:: Sy, Adama
Abstract:: Cereal crops cultivated in Mali, Mauritania and Senegal consist primarily of sorghum, millet, rice and maize. They form the gramineous crops that, are programmed for the agricultural improvement of the Senegal River Basin. Twelve economically important insect pests on these crops were selected for study and treated with regard to...

Phenotyping diverse strawberry (Fragaria spp.) germplasm for aid in marker- assisted breeding, and marker-trait association for red stele (Phytophthora fragariae) resistance marker Rpf1

Creator:: Mathey, Megan M.
Abstract:: Strawberry is one of four crops included in the USDA-NIFA Specialty Crop Research Initiative-funded RosBREED project along with apple, peach, and cherry. Phenotyping strawberry for specific horticultural and commercial traits is important to identify associations with genotypic marker(s). This process is the first step in translating genomic knowledge into enhanced...

Influence of canopy orientation on fruiting of 'Ànjou' pears and postharvest urea spray on ovule longevity and fruit set of 'C̀omice' pears

Creator:: Khemira, Habib
Abstract:: The effect of canopy orientation on fruiting performance of 'Beurre d'Anjou' pears (Pyrus communis L.) and postharvest urea spray on ovule longevity and fruit set of 'Doyenne du Comice' pears were studied. Hedgerows of 'Beurre d'Anjou' pear trees planted in 1969 in two orientations north-south (N-S) and east-west (E-W) were...

Translingual Science Communication: From Local Publications to the STEM Writing Classroom

Creator:: Werndli, Alexander J.
Abstract:: In order to assist WAC/WID practitioners and science writing faculty in incorporating translingual perspectives in disciplinary writing instruction, this study extends translingualism to language practice in the sciences by conducting a corpus study of Al-Awamia, a Moroccan agronomic journal. Mapping rhetorically significant changes across abstracts authored in English, French, and...

Relationships among phosphorus soil tests, forms of soil phosphorus, and plant uptake of phosphorus for selected southwestern Oregon soils

Creator:: Doerge, Thomas A.
Abstract:: A diversity in climate, geologic parent material, and soil characteristics exist in Jackson, Josephine, Coos, and Douglas Counties of southwest Oregon. Previous field trials and soil testing results have revealed uncertainties as to the phosphorus (P) status of the soils in this area. Twenty-four sites from nine agriculturally significant soil...

Analysis of two alternative management systems for the production of fall born beef calves in western Oregon

Creator:: Rosecrans, John Gerald
Abstract:: Two management systems were evaluated in terms of the effects on calf growth, on calf weight produced per cow per year, and on reproductive performance of fall calving cows. The alternative management systems tested were twin foster calf production and, delayed weaning, production of single suckled calves weaned at the...
