Using stable isotopes and visual gut examination to determine the diet composition of Pterostichus melanarius (Coleoptera: Carabidae) in western Oregon vegetable row crops

Creator:: Moulton, Laurel A.
Abstract:: The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...

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...

Improving initiation and mineral nutrition for hazelnut (Corylus avellana) micropropagation

Creator:: Hand, Charles R.
Abstract:: Corylus avellana L. is a global commodity and a valuable crop for the U.S. Pacific Northwest. A tremendous amount of work has been put into the development of healthy disease free, high yielding and tasty hazelnuts for the in-shell and confectionary markets. Clonal propagation is required to provide nursery trees...

Micropropagation and regeneration of hazelnut (Corylus species)

Creator:: Yu, Xiaoling
Abstract:: A micropropagation system was developed for hazelnut cultivars and rootstocks. Culture establishment was affected by explant source, explant collecting season, and type of explant. The highest frequency of culture initiation and lowest tissue oxidation and contamination were obtained from internodes with single axillary buds from grafted greenhouse-grown plants early in...

Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

Creator:: Ding, Pinghai
Abstract:: Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...

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...

Exploration of the feasibility of developing a winter hardy 'Marion' blackberry through genetic engineering

Creator:: Meng, Rengong
Abstract:: Experiments focusing on plant growth regulators’ concentrations and combination, mineral salt formulations and TDZ pretreatment formations were conducted to optimize in vitro shoot regeneration from leaf and petiole explants of 'Marion' blackberry. Optimum shoot formation was obtained when stock plants were incubated in TDZ pretreatment medium for three weeks before...

Exploring the biology and monitoring techniques of two economically impactful Chrysobothris species in Oregon hazelnuts

Creator:: Rudolph, Erica
Abstract:: Chrysobothris mali Horn and C. femorata Olivier (Coleoptera : Buprestidae) are two flatheaded wood boring beetle species that have become economically impactful pests in North American high value tree cropping systems. Both species are native to North America, with C. femorata occurring across the continent (Wellso and Manley 2007), whereas...
