RFLP analyses of interspecific hybrids of Phaseolus

Creator:: Kuo, Mei
Abstract:: Gene transfer via interspecific hybridization within Phaseolus has been limited by abnormal hybrid development and the rapid loss of hybridity in subsequent generations. The most advanced embryo development occurs in P. vulgaris x P. coccineus where mature seeds form. However, the reciprocal cross still results in abnormal embryos unable to...

Annual bluegrass (Poa annua L.) control with ethofumesate during turfgrass establishment

Creator:: Wieneche, David L.
Abstract:: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...

Substrate production of blueberry : evaluation of soilless media and potassium, nitrogen fertility on growth and nutrition

Creator:: Kingston, Patrick H.
Abstract:: As blueberry (Vaccinium sp.) production has increased in recent decades, a new interest has developed in the cultivation of blueberry in soilless substrate containers. Historically, blueberry has been propagated and grown in soilless substrate at nurseries, but nursery production is short in duration and plants are small relative to a...

Novel methods for crop load management of pear cultivars in the Pacific Northwest

Creator:: Arrington, Matthew A.
Abstract:: Novel approaches to crop load management of pear orchards in the Pacific Northwest (PNW) are necessary, but will need to vary according to the unique vegetative and reproductive growth habits of the cultivar. 'D'Anjou' is vigorous and non-precocious; thus, strategies to limit vigor and induce early fruiting are required. In...

Improving Honey Bee Health: Evaluating Efficacy and Safety of Oxalic Acid Vaporization Tactic for Varroa destructor Control and Understanding Factors Triggering European Foulbrood Disease

Creator:: Bozkus, Mustafa
Abstract:: Honey bees are vital for our food production and ecosystem due to their critical pollination services. The beekeepers in the United States and worldwide have reported significant colony losses for over fifteen years. Several stressors are implicated in these colony declines, including parasites, diseases, poor nutrition, and pesticide exposure. There...

Imaging fluorescent determination of energetics of chloroplast division and related matters

Creator:: Zheng, Ping
Abstract:: During exploration of imaging photosynthetic fluorimetry of Arabidopsis thaliana mutants, we discovered a novel phenomenon wherein photosynthetic efficiency (defined in Ning et al., 1995) is shown to plot in discrete groups. This exploration resulted first in the development of a spectrofluorometric method that apparently allows for in vivo observation of...

Genetic resistance to eastern filbert blight

Creator:: Coyne, Clarice Jean
Abstract:: Eastern filbert blight, caused by Anisogramma anomala (Peck) E. Muller, is a serious threat to hazelnut (Corylus avellana L.) production. Resistant cultivars offer the best control. Screening systems were needed to reliably identify disease, particularly in immune progeny derived from 'Gasaway'. An indirect enzyme-linked immunosorbant assay (ELISA) was developed using...

The inheritance of volatile alcohols associated with frozen bush snap beans

Creator:: Toya, Dan K.
Abstract:: Inheritance of the volatile components in bush snap beans, O.S.U. 58-110 X 'Romano' cross and reciprocal, was determined using gas-liquid chromatographic technique with gas-entrainment on-column trapping. A sample of 10 to 14 pods averaging 5 grams from a single plant was found to be adequate for F₁, F₂, and backcross...

New sources and linked AFLP markers for Eastern filbert blight resistance in hazelnut

Creator:: Chen, Honglin
Abstract:: Eastern filbert blight (EFB), caused by Anisogramma anomala (Peck) E. Miiller, is a devastating disease to orchards of the European hazelnut (Corylus avellana L.) in the Willamette Valley, Oregon. Host resistance is the most desirable means of disease control. Fifty-eight hazelnut accessions, including European cultivars and interspecific hybrids were evaluated...
