Response of Cabernet Sauvignon and Chardonnay to Fungicide Applications and Deficit Irrigation
Introduction Fungicides have been widely used on nearly every crop imaginable and are continually being developed and reformulated as more information on their efficacy on specific crops and pathogens is discovered. It is well known that fungicides are developed and used in order to have a direct effect on one or more pathogens, usually to prevent their establishment on a crop. By spraying fung...
متن کاملRegulated deficit irrigation alters anthocyanins, tannins and sensory properties of cabernet sauvignon grapes and wines.
Four regulated deficit irrigation (RDI) regimes were applied to Cabernet Sauvignon grapes, which were analyzed for phenolics and also made into wine over three consecutive growing seasons. Relative to an industry standard regime (IS), yield was reduced over the three years by 37% in a full-deficit (FD) regime and by 18% in an early deficit (ED) regime, whereas no yield reduction occurred with a...
متن کاملRegulated Deficit Irrigation Effect on Yield and Wine Color of Cabernet Sauvignon in Central California
Regulated deficit irrigation (RDI) is a management strategy that on grape can improve shoot/fruit ratio, water efficiency, and wine quality but has the potential to reduce yield. As part of a study on the influence of RDI on leafhopper density, we evaluated the effects on grape yield, berry size, berry soluble solids, and wine color. The studies were conducted at commercial vineyards in the San...
متن کاملEffects of root-zone micro-irrigation on Cabernet Sauvignon
During 2015, vines receiving season-long drip irrigation delivered into the lower root zone via hard plastic tubes yielded 70 % of commercial production while receiving only 15% of the water as the vines receiving full commercial rates of surface drip irrigation. Vines receiving direct root-zone (DRZ) irrigation at rates reduced to 60, 30, and 15% of commercial drip irrigation (DI) produced ind...
متن کاملWater Deficit Increases Stilbene Metabolism in Cabernet Sauvignon Berries
The impact of water deficit on stilbene biosynthesis in wine grape (Vitis vinifera) berries was investigated. Water deficit increased the accumulation of trans-piceid (the glycosylated form of resveratrol) by 5-fold in Cabernet Sauvignon berries but not in Chardonnay. Similarly, water deficit significantly increased the transcript abundance of genes involved in the biosynthesis of stilbene prec...
