Leaf Removal Applied to a Sprawling Canopy to Regulate Fruit Ripening in Cabernet Sauvignon

“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...

Water stress of sugarbeet as related to leaf and canopy temperatures and to leaf Water content

Exogenous 24-Epibrassinolide Interacts with Light to Regulate Anthocyanin and Proanthocyanidin Biosynthesis in Cabernet Sauvignon (Vitis vinifera L.).

Anthocyanins and proanthocyanidins (PAs) are crucial factors that affect the quality of grapes and the making of wine, which were stimulated by various stimuli and environment factors (sugar, hormones, light, and temperature). The aim of the study was to investigate the influence of exogenous 24-Epibrassinolide (EBR) and light on the mechanism of anthocyanins and PAs accumulation in grape berri...

Effects of post-flowering leaf removal on the phenolic composition of three red Vitis vinifera L. cultivars under semiarid conditions

Among seasonal practices that affect grape quality, selective leaf removal at the cluster zone is accepted as a powerful technique to manipulate flavonoid content of grapes and wines. However, most of research on fruit-zone defoliation has been conducted under temperate climate and it remains uncertain if cluster exposure would be a recommendable practice in semiarid viticultural areas. In this...
