Visualization is a useful method to teach classes in algorithms and data structures. Many animation systems of algorithms and data structures have been implemented. In these systems, students can set initial conditions, run algorithms and view the result graphically. In this project, a small visualization tool library is implemented using...
Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with precision plot sprayers. Unless otherwise indicated, preplant herbicide...

With new vineyard planting and the replanting of older vineyards on phylloxera-resistant rootstock on the rise, grape growers are looking for rootstocks that are good fits for a particular site and management style. Making an informed decision on rootstocks before planting can help create a vineyard that will be manageable...
Most quality wines are produced in areas where annual precipitation is below 700 to 800 mm (Jackson & Schuster, 1994), and evidence suggests that high rainfall or excessive irrigation lowers quality. Excessive irrigation is reported to slow ripening, increase yields partially berry enlargement, elevate juice pH and acid content, and...
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 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...
A broad range of factors influence wine grape quality and manipulation of these factors has stimulated interest among grape growers, wine makers, and research scientists alike. One such factor affecting wine grape quality is crop level, particularly for Pinot noir. Since the capacity of a vine to ripen fruit depends...
