Role of a grass riparian zone in controlling the fate of nitrogen in a poorly drained agricultural landscape

Creator:: Davis, Jennifer H.
Abstract:: Riparian ecosystems, through their unique positions in the agricultural landscape, have the potential to mitigate nutrient loading to streams. This study was conducted to gain a better understanding of N cycling in a poorly drained Grass Riparian Zone (GRZ) and adjacent Perennial Ryegrass seed Field (PRF) in the Willamette Valley,...

Inheritance and Allelism Among the B genes in Cucurbita moschata

Creator:: Wilson, Casey K.
Abstract:: One of the most economically important genes in squash (Cucurbita spp.) is the B gene which conditions precocious depletion of chlorophyll in preanthesis fruit. The B genes are found naturally occurring in at least three of the five domesticated species of Cucurbita, including C. pepo, C. maxima and, most recently...

Development of a multi-parent advanced generation inter-cross (MAGIC) population and analysis of a nested association mapping (NAM) population for improvement of genetic resistance to white mold in snap bean

Creator:: Ağır, Ahmet R.
Abstract:: Common bean (Phaseolus vulgaris L.) comes in a huge assortment of fresh and dried varieties, including snap beans, kidney beans, and pinto beans. Together, these and other market classes provide a third of the daily dietary protein in some cultures, particularly in Africa, Asia, and developing nations in the Americas....

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...

Adaptive Self-governance of Small-scale Commercial Fishers in Northeast Puerto Rico: Characterizing Formal and Informal Cooperation during Times of Crises

Creator:: Gómez-Andújar, Nicolás X.
Abstract:: Small-scale fisheries often suffer from weak, formal governance, and in response they organize in various ways. These self-organizational arrangements rely on the capacity of informal institutions, such as norms and communication, in generating social cohesion among actors in the supply chain and therefore improve the likelihood of generating commonly devised...

An Exploration of Climate Change, Conservation, and Cooperation, in Three Essays

Creator:: Johnson, Steven Mana'oakamai
Abstract:: The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...

Fisheries Connectivity Networks to Measure the Adaptive Capacity of Small-Scale Fisheries in the Baja California Peninsula, Mexico

Creator:: Nomura, Keiko
Abstract:: Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...

The Cosmetic Stay-Green Trait in Snap Bean and the Event Cascade that Reduces Seed Germination and Emergence

Creator:: Cirak, Melike
Abstract:: The persistent color (pc) trait in snap bean (Phaseolus vulgaris L.) belongs to a member of the cosmetic stay-green gene family. It is considered very desirable by snap bean breeders for its impacts on pod quality. Persistent color imparts a uniform dark-green color to pods and expresses in seeds as...

Breeding Snap Beans for Organic Agriculture: Genomic Shifts under Different Agricultural Management Systems

Creator:: King, Ryan M.
Abstract:: Although the concept of breeding crops for organic agricultural systems has been around for decades, few studies have been reported for vegetable crops to quantify and compare how conventional and organic systems differ in their selection pressures on genotypes advancing through the breeding cycle; especially research utilizing modern sequencing capabilities....

Quantitative Trait Loci and Genome Wide Association Study for Resistance to White Mold in Common (Snap) Bean.

Creator:: Arkwazee, Haidar A.
Abstract:: This is a Ph.D. dissertation for a study conducted at OSU/Horticulture. The main objective of this study was dissecting the genetic background for white mold resistance in common (snap) bean. Tow main approaches were followed to achieve the goal. The first approach was using the classical quantitative trait loci (QTL)...

Sensory Analysis and Genetic Mapping of Green Bean Flavor

Creator:: Wallace, Lyle T.
Abstract:: Green bean flavor has been studied since the 1960’s to better understand Blue Lake flavor in processed green beans in Oregon. Research by Stevens and colleagues showed that Blue Lake flavor could be reconstituted in a bland bean by adding 0.4ppm of 1-octen-3-ol and 1.6ppm of 3-hexen-1-ol. These two volatile...

A comparison of riparian zone management in Oregon and New Zealand

Creator:: Binggeli, Christian
Abstract:: Riparian areas are an integral component of fluvial ecosystems. The management of Oregon's riparian areas has come under greater scrutiny since that latest revision of the Oregon Forest Practices Act (1994). Many riparian areas lie within forested areas. Riparian management issues such as anadromous fish population decline and large woody...

Investigating the Genetic Control of Fusarium Root Rot Resistance in Snap Beans

Creator:: Huster, Abigail R.
Abstract:: Root rot diseases are a major constraint to bean (Phaseolus vulgaris L.) production around the world. Both snap beans and dry beans are affected. Root rot diseases can be caused by a variety of pathogens; however, Fusarium solani is a common causal agent. Fusarium root rot is a primary yield...

Rogue pod traits in Phaseolus vulgaris

Creator:: Al-Bader, Noor
Abstract:: Snap beans are the vegetable form of dry bean (Phaseolus vulgaris L.) with low fiber, stringless and round, succulent pods that are eaten in the immature stage. Seed companies commit significant resources to maintaining purity and uniformity of snap bean cultivars. While some variability may be introduced through outcrossing (beans...

The effect of entrance configuration on local heat transfer coefficients in subsonic diffusers

Creator:: Stoffel, Edward Oswald
Abstract:: The effects of round, square, and reentrant entrances on flow regimes and local heat transfer coefficients were determined using a symmetrical, plane-wall two-dimensional, subsonic air diffuser with one of the diverging walls heated and maintained isothermal. Flow and heat transfer studies were made at total divergence angles ranging from 0...
