Pruning and training grapevines

"The grapevine is remarkable because its vining habit can be trained in innumerable ways. Over the several thousand year history of grapevine cultivation, standard training systems have evolved in established grape-growing regions. However, new research and growers in new regions like Missouri have refined these techniques. Growers need a good understanding of the physiology of the grape plant, the differences in cultivar behavior, the characteristics of the specific soil and site, and the intended market before deciding on a training system."--First page.Larry Lockshin (Department of Horticulture, College of Agriculture)New 5/83/10
