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...

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...

Weed suppression in vegetables with residues of 'micah' barley (Horedeum vulgare L.) and other spring cereals

Creator:: Chongwe, Edgar Happy
Abstract:: Three experiments whose objectives were to investigate cover crop kill by winter freeze, weed suppression by 'Micah' barley and other spring cereals, and allelopathic potential of cereal covers were conducted at the Vegetable Research Farm and in the greenhouse and growth chamber facilities at OSU in 1989/90. Kill by winter...

Low Maintenance Strategies and Challenges within Oregon School Landscapes

Creator:: Gould, Micah A.
Abstract:: Ornamental landscapes require considerable amounts of inputs, including but not limited to irrigation, mowing or pruning, fertilization, and pest management. However, school systems have limited budgets, which reduce their access to resources and labor hours. Therefore, the objective of this project is to identify ground covers that can compete with...

Fruit color development in red pears

Creator:: Dussi Dehais, Maria Claudi
Abstract:: A fruit color descriptive study was conducted on 'Max' and 'Sensation' Red Bartlett, 'Columbia' and 'Gebhard' Red Anjou, 'Rogue Red', 'Rosired', 'Red Clapp' and 'Cascade' red pear varieties. A parallel comparative study was done to test differences between related red strains. 'Max' was compared with 'Sensation' in three different growing...

Characterization and Cultivar Susceptibility Assessment of Bacterial Blight in Hazelnut Caused by Xanthomonas arboricola pv. corylina

Creator:: Webber, John B., III
Abstract:: Bacterial blight (Xanthomonas arboricola pv. corylina) (Xac) of hazelnut (Corylus avellana L.) was described first in Oregon in 1915 and is now recognized as a damaging disease of young hazelnut trees worldwide. Stressed hazelnut trees in conditions such as planting on marginal sites, and trees between 1 and 4-years-old are...

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...

Development, detection and elimination of Verticillium dahliae in mint shoot cultures and effects of bacterial cultures and bacterization on the growth and disease development

Creator:: Wang, Nan
Abstract:: Roots of greenhouse-grown peppermint (Mentha piperita L.) and spearmint (Mentha spicata L.) plants and in vitro-grown shoot cultures were inoculated with Verticillium dahliae conidial suspensions to study symptom development, detection, and elimination of the V. dahliae. There were significant differences in the symptom expression of control and infected shoot cultures...
