Ectopic overexpression of Arabidopsis CBF genes enhances freezing tolerance of two potato species

Creator:: Pino, María-Teresa
Abstract:: Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...

Soil Water Tension Irrigation Criteria Affects Both Stevia Rebaudiana Leaf Yield and Leaf Steviol Glycoside Composition

Creator:: Parris, Cheryl A.
Abstract:: Stevia (Stevia rebaudiana) is a perennial herbaceous plant native to Paraguay and used traditionally by the native Guarani peoples for centuries to sweeten medicinal teas. Stevia has only been commercially cultivated over the past 50 years and cultural practice information suitable for implementation by growers is limited. Currently stevia’s commercial...

Managing Microdochium Patch Using Non-Traditional Fungicides on Annual Bluegrass Putting Greens

Creator:: Mattox, Clint M.
Abstract:: Currently, fungicide applications are the predominant method of control for the cool weather pathogen Microdochium patch (Microdochium nivale). Increasing pesticide restrictions have generated concern regarding management of Microdochium patch. Three separate field trials exploring non-traditional fungicides were conducted between 2013 and 2015 on an annual bluegrass (Poa annua L.) sand-based...

Cover crop effects on root rot of sweet corn and soil properties

Creator:: Miyazoe, Mikio
Abstract:: Root rot of sweet corn in western Oregon and Washington is a significant disease that can reduce yield of intolerant cultivars of processed sweet corn by fifty percent. Root rot is caused by a complex of soilborne organisms, including Drechslera sp., Phoma terrestris, and Pythium arrhenomanes. Processors have adopted tolerant...

Effect of temperature and zinc on development of tobacco mosaic virus in resistant and susceptible tomatoes

Creator:: Lopez-Garcia, Justo
Abstract:: An investigation of the effects of temperature and of zinc on development of tobacco mosaic virus (TMV) in resistant and susceptible varieties of tomatoes was conducted under greenhouse conditions. The study included two experiments, one run during late winter and early spring, and the other during late spring and summer,...

Effects of planting bush beans (Phaseolus vulgaris L.) in single or double rows

Creator:: Mhaka, Amon Gwaziva
Abstract:: A comparison was made between double rows 15 cm apart on 76 cm centers and single rows 76 cm apart of 'Oregon 91G' bush green beans at the same planting densities in three experiments in 1986 and 1987. There was a significant increase in yields of pods from double rows...

Evaluation of allelopathy as a mechanism by which buckwheat suppresses Canada thistle and its mycorrhizae

Creator:: Eskelsen, Steven R.
Abstract:: Experiments were conducted to determine if allelopathy is a mechanism by which buckwheat interferes with a) the growth of Canada thistle and/or b) mycorrhizae colonization in Canada thistle roots. In a competition experiment, buckwheat plant biomass was only affected by the intraspecific competition from other buckwheat plants and not by...

Enhancement of the weed competitive ability of lowland rice (Oryza sativa L.) cultivars

Creator:: Ranasinghe, Lakshman L.
Abstract:: Most of the presently grown cultivars of rice (Oryza sativa L.) have poor competitive ability against weeds if compared with traditional cultivars. Therefore, effective weed control is an important but often costly and difficult management practice in rice crop production. If weed competitive ability of rice cultivars could be improved...

Efficacy of Cultural Practices for Mitigating the Negative Impacts of Grapevine Red Blotch Virus on Vine Physiology and Fruit Composition in Oregon Pinot Noir

Creator:: Copp, Cody R.
Abstract:: The recently emerged Grapevine Red Botch Virus (GRBV) impedes proper berry ripening primarily by reducing sugar accumulation and color development in red-fruited Vitis vinifera L. cultivars. To date, there is no recommended management strategy for virus spread or the impacts of the disease beyond removal and replacement of infected vines....
