Water 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...
متن کامل“Tannin in skins and seeds of Cabernet sauvignon, Syrah, and Pinot noir berries during ripening”
Tannins are the most abundant type of phenols in grapes. Because they include a vast collection of chemical structures, measuring them is a huge task. But fortunately, it may not be necessary to know how much of each species of tannin is there in a wine. It would seem sufficient, for practical purposes, to be able to know how much of that tannin plays a role in a wine’s astringency. This is wha...

متن کاملResponse 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 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...
