Raisin yields, average berry weights, soluble solids, and total acid determinations were taken for 3 years.Raisin yields were usually significantly increased with the horizontal or flat-top trellis. In one test, increased yield was partially due to higher soluble solids. The increase in yield was probably due to a greater number of berries which would result from more clusters and/or larger clusters.The increase in the number of berries might be due to more mature renewal fruit canes. Shoots used for renewal canes are supported by the wires in a horizontal trellis and thus are better exposed to light than with a one-wire trellis, where these shoots hang downward and are often shaded.Expanse of the leaf area is greater with a horizontal or wide-top trellis than with a single wire trellis. The horizontal trellis also spreads and supports the shoots, which should provide for better leaf exposure.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/16/4/237}, eprint = {https://www.ajevonline.org/content/16/4/237.full.pdf}, journal = {American Journal of Enology and Viticulture} }
