Breeding Snap Beans for Organic Agriculture: Quantification and Application of Key Traits

Creator:: Park, Hayley E.
Abstract:: Improving crop cultivars for use on organic farms is pertinent, as current elite germplasm is less resilient within the more variable context of organic farm environments. Although a growing number of studies have focused on organic plant breeding in cereal crops, very few have focused on vegetable crops, especially those...

High-density Linkage Maps for European Hazelnut (Corylus avellana L.) from Single Nucleotide Polymorphism Markers and Mapping New Sources of Resistance to Eastern Filbert Blight

Creator:: Komaei Koma, Golnaz
Abstract:: European hazelnut (Corylus avellana L.) is a diploid with 11 pairs of chromosomes (2n = 2x = 22), monoecious, dichogamous and wind-pollinated. Eastern filbert blight (EFB) caused by Anisogramma anomala is a serious disease of European hazelnut (Corylus avellana) in North America, and infection leads to cankers that girdle branches...

Spatiotemporal Phytohormone Distributions in Developing Pinot Noir Berries and the Effects of Two Viticulture Practices Thereon

Creator:: Schmidt, Joseph A.
Abstract:: In recent years, many studies have focused on the molecular and biochemical mechanisms regulating the development of wine grapes. The course of grape berry development is directed by genetic design and is mediated by phytohormones, which regulate grape berry growth and development by orchestrating a complex network of interacting genes,...

The Primary Disease Gradient of Wheat Stripe Rust (Puccinia striiformis f. sp. tritici) Across Spatial Scales

Creator:: Farber, Daniel
Abstract:: Wheat stripe rust (WSR), also called yellow rust of wheat (Tricitum spp.), causal agent Puccinia striiformis f.sp. tritici (Pst), is a foliar disease of major economic importance on wheat, especially grown in temperate locations. WSR causes major losses of wheat yield, estimated at nearly $ 1 billion per year, and...

Transcriptome Responses of the Nitrifying Bacteria Nitrosomonas europaea and Nitrobacter hamburgensis to Low Oxygen

Creator:: Dobie, Michael
Abstract:: Nitrification is the process within the global Nitrogen Cycle where ammonia (NH3) is oxidized to nitrate (NO₃⁻) and can be carried out by two distinct groups of bacteria. The ammonia-oxidizing bacteria (AOB) first oxidize NH₃ to nitrite (NO₂⁻), and second, the nitrite-oxidizing bacteria (NOB) oxidize NO₂⁻ to NO₃⁻. In aerobic...

Mulching to Manage Mummy Berry of Blueberry

Creator:: Florence, Jade
Abstract:: Monilinia vaccinii-corymbosi pseudosclerotia overwinter on the soil surface and produce apothecia in early spring, providing primary inoculum for Mummy Berry Disease of blueberry. Burial under 2.5 cm of soil or the absence of light have previously been identified as critical factors preventing the development of apothecia. Mulches were applied to...

Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

Overwintering survival of stem rust on perennial ryegrass : construction of a simulation model, and effects of the mycoparasite Sphaerellopisis filum

Creator:: Gordon, Tyler C.
Abstract:: Stem rust, caused by the fungus Puccinia graminis subsp. graminicola, can cause yield reductions exceeding 90% on perennial ryegrass (Lolium perenne L.) crops grown for seed if not treated with fungicide in the spring. There is evidence that late-spring stem rust epidemics are initiated by populations that survived the winter....

Evaluation of genetic diversity in wild populations of black raspberry (Rubus occidentalis L.)

Creator:: Dossett, Michael
Abstract:: In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred, in part, by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are...

Effects of refrigeration storage and processing technologies on the bioactive compounds and antioxidant capacities of blackberries ('Marion' and 'Evergreen')

Creator:: Wu, Ruyi
Abstract:: The objective of this project was to investigate the effects of refrigeration storage and processing technologies on the quality and nutraceutical benefit of blackberries. 'Marion' and 'Evergreen', the two major blackberry varieties in Oregon, were evaluated in this study. For refrigeration storage, fresh fruit were packed in clam-shell containers right...
