Developing Tools to Utilize the Oregon State University Woody Plant Collection and Establish a Campus Arboretum

Creator:

Blanchard, William D.

Abstract:

Oregon State University campus grounds have long been admired for their beauty and the diversity of over 65,000 individual woody plants that grace the 570 acres of campus. The woody plant collection has provided a living learning laboratory for the university and surrounding community for decades. The campus grounds include...

Masters Thesis
The Effects of Ploidy Manipulation on ‘I3’ hemp

Creator:

McLeod, Adigun

Abstract:

Hemp is a dioecious, annual, flowering plant in the Cannabaceae family. It has been used for thousands of years to produce textiles, essential oils, and medicines. The overall purpose of these experiments was to propagate the cannabinoid-free cultivar, ‘I3’, and follow up by inducing polyploidy in the ‘I3’ hemp via...

Fingerprinting, reproductive behavior and pollinator dynamics of Buddleja davidii and interspecific hybrids

Creator:

Still, Cara M.

Abstract:

Buddleja davidii (butterfly bush) is a highly adaptable landscape plant known for pollinator attraction. Unfortunately, it is also regarded as an invasive plant in highly disturbed environments across the globe. It is an invasive species in Oregon, officially classified as a class B noxious weed in 2004. Currently the state...

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 –...

Developing Tools for Hardy Hibiscus and Lilac Breeding: Quantile Regression, Cytogenetics, Interspecific Hybridization, Somatic Hybridization, and Marker-Trait Association

Creator:

Chen, Hsuan

Abstract:

Hibiscus and lilacs (Syringa spp.) are economically important nursery crops in the US that accounted for 4.5 million units ($30 million) and 2 million units ($20 million), respectively (USDA, 2016). To maintain and expand the market share of ornamental plants such as lilacs and Hibiscus, novel performance, floral ornamental value,...

Dissertation
Prunus laurocerasus: A Study of Reducing Gamete Development through Haploidy and Determining Cytotype Variability in Pollen

Creator:

Seely, James T.

Abstract:

Prunus laurocerasus, commonly known as cherrylaurel, is a woody shrub grown in temperate climates for its durability and landscape appeal. Due to its abundance of drupes that are spread by birds, cherrylaurel is a litter nuisance in cultivation and also has escaped cultivation such that it has naturalized. Furthermore, it...

Undergraduate Thesis
Breeding, Production, and Morphophysiology Among Cytotypes of Common and Portuguese Cherrylaurel

Creator:

Schulze, Justin A.

Abstract:

The common cherrylaurel (Prunus laurocerasus) and Portuguese cherrylaurel (P. lusitanica) are economically important landscape shrubs across the United States. To gain a better understanding of physiology and morphology in these higher level polyploids (P. lusitanica, 2n = 8x; P. laurocerasus, 2n =22x), a variety of breeding experiments were performed. The...

Genome sizing and fire blight resistance screening in Cotoneaster

Creator:

Rothleutner, Joseph J.

Abstract:

Cotoneaster is an ornamental shrub valued for showy flowers, berries and architecture as well as the ability tolerate adverse conditions under which other taxa fail. Cotoneaster is a highly diverse genus of over 400 species, of which few are available in the US nursery trade. Some species commercially available have...

Masters Thesis
Identification of quantitative trait loci underlying kernel extra-softness and related traits by linkage and association mapping in wheat (Triticum aestivum L.)

Creator:

Wang, Guomei

Abstract:

Kernel hardness (KHA) is a major factor determining break flour yield (BFY) and end-use quality of common wheat (Triticum aestivum L.). Within the soft wheat class, genotypes with consistently softer grains than common soft wheat are considered to be 'extra-soft'. In addition, 'extra-soft' wheats have greater BFY than common soft...
