Effects of Vineyard Managements on Grape and Wine Quality in Response to Grapevine Red Blotch Disease

Creator:: Huang, Ling
Abstract:: Grapevine red blotch virus (GRBV) is a single-stranded DNA virus that causes grapevine red blotch disease (GRBD). Symptoms of GRBD include red discoloring of leaf margins and red veins on the underside of the leaves. GRBD affects the plant's metabolism and photosynthetic pathways, and disrupts carbon translocation and chlorophyll concentrations....

Fruit quality evaluation of strawberries (Fragaria ananassa) grown in California and Oregon

Creator:: Jetti, Rajesh R.
Abstract:: Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...

The effect of hopping technology on lager beer flavor and flavor stability and the impact of polyphenols on lager beer flavor and physical stability

Creator:: Aron, Patricia M.
Abstract:: Beer is one of the most extensively consumed beverages world-wide and it is almost always brewed with hops (Humulus lupulus, L.). Hops provide beer with bitterness, aroma, flavor and texture and also enhance specific beer properties such as foam stability, clarity (colloidal stability), color, flavor stability and microbial stability. Hops...

Impact of Preharvest Weathering, Without Sprouting, on the Quality of Soft White Winter Wheat in the U.S. Pacific Northwest

Creator:: Smith, Jordan L.
Abstract:: When wheat is exposed to rain in the period before harvest, it sometimes causes the problem of pre-harvest sprouting (PHS). Wheat that undergoes sprouting has poor end-use quality and is less valuable. In recent years, the U. S. Pacific Northwest (PNW) has experienced increased summer showers sometimes causing widespread PHS....
