Inducing and Evaluating Phenotypic and Cytometric Variation in Landscape Plants : Observations from Acer, Ornithogalum, and Penstemon

Creator:: Lattier, Kim Shearer
Abstract:: Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....

Effect of row cover and supplemental Ca fertilization on blossom-end rot in bell pepper (Capsicum annuum var. annuum, Grossom Group)

Creator:: Alexander, Shara E.
Abstract:: A 2-year trial was conducted at Oregon State University's Hermiston Agricultural Research and Extension Center to examine the effects of spunbonded row cover and supplemental calcium fertilization on blossom-end rot in two varieties of bell pepper. Blossom-end rot is a common cause of bell pepper yield losses, especially at the...

Effects of tillage-induced soil compaction on carrot seedlings emergence and yield

Creator:: Thomasson, James E.
Abstract:: The effects of five tillage treatments on soil bulk density and mechanical impedance were examined on Newburg sandy loam soil in the Willamette Valley, Oregon, in 1987. Subsequent effects on seedling emergence and yield of carrots (Daucus carota L., cvs. Orlando Gold and Royal Chantenay) were also measured. Mechanical impedance...

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...

Phenotyping Ornamental Plants: Case Studies in Fruit Quality Attributes from Vaccinium ovatum and Disease Resistance of Cotoneaster spp.

Creator:: Neill, Kristin E.
Abstract:: Landscape plants are highly diverse and nursery producers often grow thousands of taxa to satisfy the varied needs and aesthetic tastes of consumers. Related to this diversity, ornamental plant breeders must be nimble and diverse in their approach. Two seemingly disparate studies were conducted to investigate improving ornamental shrubs –...

Variation and heritability of vegetative, reproductive and fruit chemistrytraits in 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 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 ill adapted...

Girdling and shading effects on inflorescence necrosis and rachis composition of pinot noir grapevine

Creator:: Ibacache, Antonio E.
Abstract:: There are several grape disorders that reduce fruit set. One, millerandage, is from poor fertilization to produce "hen and chicken" or small seedless berries; while another, Coulure, is the failure of grape flowers to develop into berries. A third one, inflorescence necrosis (INec), is a disorder that should be in...

Non-nutritive Sugars as a Management Tactic for Spotted-Wing Drosophila (Drosophila suzukii) and Non-Target Effects

Creator:: Price, Briana E.
Abstract:: With confirmation of non-nutritive sugar, erythritol, having insecticidal properties to Dipterans, this thesis research focuses on use of erythritol as a human-safe management tool for small berry and cherry pest, Drosophila suzukii, commonly referred to as spotted-wing drosophila. Drosophila suzukii is a destructive invasive fruit fly from Asia with an...

Farmer perspectives on success and challenges : a study of small farms in Oregon's Willamette Valley

Creator:: Pool, Kristin E.
Abstract:: This thesis investigates the success of and challenges facing small farmers operating direct marketing farm businesses in Oregon's Willamette Valley. This qualitative study utilizes participatory methods to gain the unique perspectives of small farmers regarding their success and challenges. Small farms are important players in local food systems and ensuring...

Phylogenetic Estimation and Ancestral State Reconstruction of Rubus (Rosaceae) using Target Capture Sequencing

Creator:: Carter, Katherine A.
Abstract:: Hybridization, polyploidy, and apomixis have made phylogenetic estimation in Rubus challenging. I used target capture to sequence approximately 1000 low copy nuclear loci and the chloroplast genome for 94 accessions representing the genus Rubus and distributed worldwide. Species phylogenies were estimated using two coalescent based methods, ASTRAL-II and SVDQuartets, and...
