Factors affecting stand establishment and yield of meadowfoam (Limnanthes alba Benth.)

Creator:: Nyunt, San
Abstract:: Germination of meadowfoam (Limnanthes alba Benth.) seed is inhibited by warm soil temperatures. This has led to recommendations for planting from early to mid-October when soil temperatures are below about 15°C. Objective data on the effects of planting date on stand establishment and yield are not available. These studies were...

Germination and dormancy of meadowfoam seed

Creator:: Mmolawa, Onesimus B.
Abstract:: Meadowfoam (Limnanthes spp.) is a potential oil seed crop being developed for commercial production in the Willamette Valley. The seeds are characterized by poor germination at warm temperatures. It would be desirable to overcome this temperature-related dormancy problem so that better stand establishment could be realized from early fall planting....

The Biology and ecology of weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana)

Creator:: Tarasoff, Catherine
Abstract:: Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is native to semi arid environments of western North America. These species are often referred to collectively as ‘alkaligrass’; however, for farmers...

Crossing behavior, RAPD analysis and chlorophyll flourescence in relationship to the geographic adaption of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: García de los Santos, Gabino
Abstract:: Birdsfoot trefoil (Lotus corniculatus L.) is a popular perennial, non-bloating forage legume used for pasture, hay and silage throughout the temperate regions of Europe, Asia Minor, North Africa and North and South America. It is regarded as the most morphologically and biochemically variable species in the genus. Research investigating the...

Genetic factors that provide adult plant resistance against Puccinia striiformis f. sp. tritici to wheat cultivar 'Stephens' in a multilocation analysis.

Creator:: Vazquez, Maria Dolores
Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving increased attention in the USA since the appearance of more virulent races detected in the past decade. These races caused yield losses even in areas where the disease previously was rarely detected. Host plant resistance is the most cost effective...

From the Oregon Wolfe Barley to fall-sown food barley : markers, maps, marker-assisted selection and quantitative trait loci

Creator:: Chutimanitsakun, Yada
Abstract:: Understanding complex traits is a fundamental challenge in plant genetics and a prerequisite for molecular breeding. Tools for trait dissection are markers, maps, and quantitative trait locus (QTL) analysis. Marker-assisted selection (MAS) is an application that integrates these tools. In this thesis research, a new sequence-based marker was evaluated, maps...

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...

Identifying Quantitative Trait Loci for Resistance Against Stripe Rust and Septoria tritici blotch in Soft White Winter Wheat

Creator:: Cobertera, David
Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) and Septoria tritici blotch (Zymoseptoria tritici) are a constant and significant threat to wheat production, significantly reducing wheat quality and yield. Wheat is responsible for 20% of the world’s human calorie intake, and wheat production must increase to supply the demand of the...
