Riesling vines were subjected over a 3-year old period to four training systems ('flachbogen'; 'pendelbogen'; low cordon; Moselle loop) in combination with two pruning strategies (30 + 10 balanced pruning; 25 nodes/m of row). Low cordon-trained vines yielded highest and maintained densest canopies, but were also characterized by a reduction in cane periderm formation, wine aroma intensity, wine quality, and, during 1984, 0 Brix, duster weight, and berries per duster. Effects of both training and pruning strategy on titratable acidity and pH were very small. Due to large and consistent gains in yield, improved budbreak and canopy fill, as weil as potential for mechanization of pruning, low cordon training is recommended for Riesling on non-divided canopies.Downloads
