The conservation of open space will become increasingly important as populations expand and undeveloped land is converted to urban uses. The benefits derived from open space conservation include protecting and improving water quality, providing wildlife habitat, maintaining scenic amenities and rural character, and supplying certain recreational opportunities. This study utilizes...
Three different green cover treatments were compared in their effect on leaf gas-exchange, vine growth, yield and fruit composition. The treatments were: grass cover, resident plants, and an insectary plant mixture. Photosynthesis, transpiration, and water use efficiency were lower for vines with a grass cover. Leaf area and shoot growth...
Pinot noir and Chardonnay are the two main varieties in Oregon. Together they comprise approximately 60% of the Oregon winegrape acreage, and 64% of the total production for a value of $10,482,000 (69%). Internationally, clonal selection of Pinot noir and Chardonnay have made available, for each variety, an array of...
Five replicated rootstock trials established in Oregon's three main viticultural regions were evaluated for the effect of rootstock on Pinot noir performance. All the trials except Alpine included the following seven rootstocks: ungrafted Pinot noir, 3309 Couderc, 101-14 Millardet et De Grasset, 44-53 Malegue, 420 A Millardet et De Grasset,...

The introduction of new clones and rootstock varieties has played an important role in the development of the Oregon wine grape industry. The OSU Grapevine Mother Block has been an integral part of this overall vine improvement program providing a readily accessible source of specific pathogen tested grapevine plant material...

Pinot noir and Chardonnay are the two main winegrape varieties in Oregon. In 1997, they comprised approximately 58% of the Oregon winegrape acreage, and 60% of the total production for a value of $14,171,000 (66% of total) (1). Internationally, clonal selection of Pinot noir and Chardonnay have made available, for...
Pinot noir and Chardonnay are the two main winegrape varieties in Oregon. In 1998, they comprised approximately 59% of the Oregon winegrape acreage, and 57% of the total production for a value of $10,803,000 (62% of total) (1). Internationally, clonal selection of Pinot noir and Chardonnay have made available, for...
The effect of shoot tipping, lateral shoot length and cluster zone leaf removal on yield, yield components, fruit composition and soundness were evaluated on mature Pinot noir grapevines. Shoot tip removal at bloom improved percent fruit set, number of berries per cluster and cluster weight. Elimination of lateral shoots also...
