Assays to determine tolerance of cherry rootstock to bacterial canker caused by Pseudomonas syringae pv. syringae

Creator:: Krzesinska, Elzbieta Z.
Abstract:: Bacterial canker, caused by Pseudomonas syringae pv. syringae is recognized as one of the greatest limiting factors in cherry production in Oregon. Disease incidence may be decreased when susceptible cultivars are high-grafted onto tolerant/resistant rootstocks. This research was begun to develop a rapid screening method which could be used to...

Development of an in vitro and modification of an in vivo bioassay to screen cherry genotypes for response to inoculation with Pseudomonas syringae pv. syringae

Creator:: Roche, M. Margaret
Abstract:: The bacterium Pseudomonas syringae affects different crops worldwide. In the Willamette Valley of Oregon, P. syringae causes bacterial canker in sweet cherry, severely limiting its production. High grafting of susceptible sweet cherry cultivars to resistant rootstocks is practiced in the Willamette Valley to reduce incidence of this disease. The research...

Inheritance of resistance to the lentil strain of pea seedborne mosaic virus in Pisum sativum L.

Creator:: Kasimor, Kathryn T.
Abstract:: The inheritance mode of pea-resistance to the Lentil Strain of Pea Seedborne Mosaic Virus (PSbMV-L) was studied. In addition, commercial pea cultivars, Plant Introduction (P.I.) lines and Oregon State University (OSU) breeding lines were tested for susceptibility to this virus. These lines were also tested for their reaction to Bean...

Plant hormone-induced defense responses against Botrytis cinerea

Creator:: Akagi, Aya
Abstract:: Several plant hormones, including ethylene and jasmonates, are known to mediate responses against biotic and abiotic stress. The first and second objectives of this thesis were (i) to elucidate the role of ethylene in defense responses against Botrytis cinerea and specifically (ii) to determine the potential contribution of ethylene response...

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...

Detection, identification, and antibiotic treatments of bacterial contaminants from micropropagated strawberries

Creator:: Tanprasert, Piyarak
Abstract:: Bacterial contamination is one of the most important problems both in plant tissue culture research and commercial laboratories. Early detection of contaminants saves time, effort, and money. Strawberry runner explants were screened for contaminants during June to August, 1994 and 1995. Most contaminants found were bacterial rather than fungal. Bacterial...

Population dynamics, distribution, and control of nematodes in highbush blueberries

Creator:: Schroeder, Jan-Marie
Abstract:: Fluctuations in population density of Pratylenchus sp., Trichodorus sp., and Xiphinema americanum s. 1. in three blueberry fields were determined monthly for one year. Pratylenchus densities were greatest in August and least in October. Three distinct periods of population growth occurred; during January, April, and between June and August. Trichodorus...

Traditional and molecular approaches to Zucchini yellow mosaic virus resistance in Cucurbita

Creator:: Brown, Rebecca Nelson
Abstract:: Zucchini yellow mosaic virus (ZYMV) is an important disease of Cucurbita worldwide. Resistant cultivars are the best means of control. ZYMV resistance is quantitative in the wild species C. ecuadorensis, and is controlled by at least three genes in tropical C moschata. Very little molecular work has been done in...

DNA markers linked to novel sources of resistance to eastern filbert blight in European hazelnut (Corylus avellana L.)

Creator:: Sathuvalli, Vidyasagar R.
Abstract:: The hundred-year history of the hazelnut industry in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. Marker-assisted selection (MAS) has been extensively used for ‘Gasaway’ resistance in the hazelnut breeding program at Oregon State University. Concern over breakdown of...
