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...

Phenotyping diverse strawberry (Fragaria spp.) germplasm for aid in marker- assisted breeding, and marker-trait association for red stele (Phytophthora fragariae) resistance marker Rpf1

Creator:: Mathey, Megan M.
Abstract:: Strawberry is one of four crops included in the USDA-NIFA Specialty Crop Research Initiative-funded RosBREED project along with apple, peach, and cherry. Phenotyping strawberry for specific horticultural and commercial traits is important to identify associations with genotypic marker(s). This process is the first step in translating genomic knowledge into enhanced...

Development of volatile compounds in Pinot noir grapes and their contributions to wine aroma

Creator:: Fang, Yu
Abstract:: It is often perceived that late maturity of grape gives a more complex aroma profile to Pinot noir wine, however, there is little understanding of the basic flavor chemistry of grape maturity on wine aroma. The aroma contributing compounds in Pinot noir were first identified by aroma extract dilution analysis...

Statistical Methods for Tissue Culture Medium Optimization and A Multiplexed Fingerprinting Set for Hazelnuts

Creator:: Akin, Melekşen
Abstract:: Hazelnut is one of the most important nuts in worldwide production and the European hazelnut (Corylus avellana L.) is the most economically important of the 11 recognized hazelnut species. Development of new cultivars is continuous, with emphasis on better nut quality, high yield and disease resistance. Hazelnuts are highly heterozygous,...

Water partitioning and respiration activity of dormant grape buds

Creator:: Gardea, Alfonso A.
Abstract:: Dormancy of 'Pinot Noir' grapevines was characterized. Primary buds required ca 300 cumulative chilling hours (CCH) to initiate the transition from endodormancy to ecodormancy, which occurred in mid November. Additional chilling, up to 1000 CCH, improved budbreak. Changes in bud water content were estimated by gravimetric and spectroscopic methods. Total,...

Comparative Genomics of Different Races of Columbia Root-knot Nematode and Development of Molecular Markers Linked to Corky Ringspot Resistance in Potato

Creator:: Hu, Shengwei
Abstract:: On a global scale, potato (Solanum tuberosum L.) plays an important role in tackling the threat of food insecurity due to its high yield and broad global acceptance. However, pathogens threaten potato production, causing direct yield loss and rendering potatoes tubers unmarketable. Breeding new cultivars that carry multiple resistances is...

Characterization of factors affecting pectinmethylesterase activity in cucumber fruit

Creator:: Turk, Farzaneh
Abstract:: Pectinmethylesterase (PME) activity in fresh cucumber fruit was determined. The effects of several cationic species, temperature, pH, and acetic acid on the activity of cucumber PME was investigated. The efficacy of blanching, infiltration with CaCl₂ or acetic acid, and fermentation with 0 and 40 mM CaCl₂ on inhibition of cucumber...

Genome Resource Development for Advancement of Corylus avellana Breeding

Creator:: Talbot, Samuel Corcoran
Abstract:: The European hazelnut (Corylus avellana L.) is a tree nut crop that is important in Oregon, which produces 99% of the United States’ hazelnuts but only 5% of the world’s supply. In order to maintain this market share, farmers in Oregon need cultivars that produce high quality nuts, mature early,...

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...

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...
