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...

Polyphenol oxidase (PPO) from strawberries was purified,
partially characterized, and used to study its role in the degradation
of anthocyanin pigments. The extraction method included the use of a
buffered solution containing the phenolic binders Polyclar AT and
Amberlite XAD-4. Addition of Triton X-100 resulted in an increase of

Two experiments were conducted from 1987 to 1990 to study the effect of date of renovation on strawberry yield and yield components. In the first experiment, 'Benton' plants were renovated from July 6, 1988 (1 week after harvest - WAH) to August 24, 1988 (8 WAH). In the second experiment...
This dissertation describes the application and development of molecular tools that have great potential for use in studying variation in strawberry germplasm. The first study evaluated 91 microsatellite (simple sequence repeat, SSR) markers for transferability in 22 Fragaria species and their utility in fingerprinting octoploid strawberries. Out of the transferable...

Recent research shows that flower parts of strawberry (Fragaria X ananassa Duch.) differ in their capacity to support the growth of Botrytis cinerea, the fungus which causes gray mold on fruit. Growth in styles is slow and hyphae rarely enter the carpel (achene), suggesting that this pathway is not the...

The western states include a complex combination of geological, topographical, climatic, and vegetative features. The region extends through 1900 km of latitude and contains three major north-south, storm-directing mountain systems. Most of the region is arid (annual precipitation < 50 em); however, sizeable agriculturally important areas west of the Cascade...

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,

Strawberries {Fragaria ananasa) and raspberries {Rubus ideaus) are good sources ofmany important nutrients, and have great potential to improve human health. However, they are highly perishable and have a very short shelf-life mainly due to the attack of fungi and high respiration rate. Edible coatings, especially chitosan-based coatings have been...
Understanding the impact of humans on the environment has long been a topic of scholarly interest and debate. As environmental problems mount, accounts of historic ecological conditions and the factors of change become increasingly useful. This study considers competing schools of interpretation about human impacts on ecological landscapes and develops...
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...
The effects of fenamiphos on soil and root populations of Pratylenchus penetrans were evaluated in four red raspberry cv. Willamette fields in Northwestern Oregon. Field 1 was a silty clay loam with 53% organic matter (OM). Field 2 and 3 were silty loam soils with 3.25 and 2.55% OM, respectively...
Raspberries are an important commodity worldwide, with the United States (U.S.) leading fourth in global production in 2017. An important factor when shipping propagated Rubus across the globe is the security of clean plant material verified through pathogen detection methods which is vital in preventing disease spread.
