This study investigated the effects of four trellis styles (Geneva double curtain, high cordon, Smart-Dyson, and vertical shoot positioned) on the fruit-zone light environment, fruit chemical composition, and yield of ‘Frontenac’ grapevines (Vitis spp.) grown on a fertile site near Crete, Nebraska over two growing seasons. Photosynthetically active radiation was measured above the canopy and within the fruiting zone at berry set, veraison, and harvest. At all sampling dates in 2008, vines grown on Geneva double curtain and high cordon had higher mid-day transmittances than vines grown on Smart-Dyson and vertical shoot positioned. In 2009, transmittance relationships among training systems were similar. In both years, leaf layer number was lower for Geneva double curtain and high cordon than for Smart-Dyson and vertical shoot positioned. In 2008, Geneva double curtain vines had higher fruit yield than vertical shoot positioned, Smart-Dyson, and high cordon. In 2009, Geneva double curtain yielded more than vertical shoot positioned and high cordon. In 2008, Geneva double curtain had higher pH and °Brix than other trellises; titratable acidity was lower in Geneva double curtain and high cordon than in Smart-Dyson and vertical shoot positioned. In 2009, fruit composition results were not related to transmittance. We propose Geneva double curtain training as a viable choice for Midwestern growers.

As winter progresses in Nebraska, the supply of affordable strawberries decreases while the demand increases, particularly during the winter holiday season. This presentation will report on experiments involving 13 cultivars of strawberries grown in a double polyethylene greenhouse during Spring 2010 and Fall 2010 through Spring 2011. The plants were grown on capillary mats covered with white reflective plastic. Heat was supplied by poly tubes located under each of two benches. The purpose of these experiments was to determine which cultivars would yield the greatest mass and number of berries. Strawberry cultivars were also tested for their nutraceutical properties and sugar content. Nutraceutical data from Spring 2010 indicated a tight range in total phenols (1.06–1.84 mg/g) with nine of the cultivars showing significant differences if compared to the very lowest level. A similar situation occurred with total flavonoids (0.28–0.62 mg/g). The antioxidant capacity, however, showed a large separation with ‘Strawberry Festival’ and ‘Darselect’ (73–75 uM/g) having significantly more antioxidant capacity than ‘Honeoye’, ‘Albion’ and ‘AC Wendy’ (32–49 uM/g). Fall–Winter 2010 production peaked during the weeks of December 4 and 11 with ‘Albion’, ‘Chandler’, ‘Darselect’, ‘Clancy’, and Seascape’ producing the greatest total berry mass and numbers. Production information including sugar content, total berry mas,s and numbers for both years will also be presented.
