Effect
Acadian treated Grapevine, cv. Sangiovese, grown in an orchard in Italy had on average the same yield, 4.2 % less clusters/vine, a 3.9 % higher cluster weight, 2.5 % less soluble solids, a 1.6 % lower pH, a 3.7 % higher titratable acidity, 29.6 % more skin total anthocyanins and 33.8 % more skin total phenolics compared to the untreated control. The lowest dose had best effect. Acadian treated Grapevine, cv. Pinot Noir/Cabernet Franc, grown in an orchard in Michigan had on average a 7.8 % longer shoot, a 7.5 % smaller leaf area, a 2.2 % higher leaf specific weight, 2.3 % more leaf dry matter, 25.6 % more leaf soluble sugars (sign), 29.2 % less leaf starch, a 3.3 % lower yield, 1.4 % less clusters/vine, a 2.1 % higher cluster weight, 2.8 % less berries/cluster, 5.3 % heavier berries, a 2.6 % higher skin/pulp ratio, 6.9 % more berry skin dry matter, 18.5 % less bunch rot incidence, a 10 % lower bunch rot severity, 1.9 % more soluble solids, a 2.9 % higher titratable acidity, 9.4 % more skin total anthocyanins (sign) and 2.6 % more skin total phenolics compared to the untreated control.
