The color of grapevine berries is one the most important quality parameters that define appearance, attracts consumer, and determines price, especially in red grape cultivars. Some varieties show less development due to many factors such as temperature, light intensity, agricultural management. present study aimed evaluate diverse phytohormones coupled with grafting on fruit coloration ’Crimson...

The responses of two red grape varieties, Bovale Grande (syn. Carignan) and Cannonau (syn. Grenache), to temperature and natural UV radiation were studied in a three-years field experiment conducted in Sardinia (Italy), under Mediterranean climate conditions. Vines were covered with plastic films with different transmittances to UV radiation and compared to uncovered controls. Light intensity a...

to evaluate effects of gibberllic acid, gridling, berry and bunch thining and their combination on fruit maturity, berry and bunch characteristics of grape cv. yaqooti an experiment was carried out using randomized complete block design with three replications in kavar, shiraz, iran, in 2010-2011 growing season. each experimental plot consisted of three vines. treatments included: t1: gibberlli...

Anthocyanins are antioxidants and are among the natural products synthesized via the flavonoid biosynthesis pathway. Anthocyanins have been recommended for dietary intake in the prevention of cardiovascular diseases, cancer, and age-related conditions such as Alzheimer's disease or dementia. With an increasingly aging population in many parts of the world, strategies for the commercial producti...

Many vineyards all over the world can easily produce high potential alcohol levels, but the importance of the sugar content in berries has been changing over the past few years. The objective of this work was to reduce the sugar and pH of the grapes, delay berry ripening by decreasing the ratio between the leaf area and yield, perform an intense trimming treatment after berry set and establish ...

BACKGROUND: Small berry size is normally associated with quality wine production. However, the contribution of grapevine variety and environment to sensory has not been well established. In this study, genotypes from two intra-specific hybrid populations were categorized by according diameter weight: small ( 16 mm, >2 g). Chemical attributes wines produced in consecutive vintages (2017 2018) ea...

Light environments have long been known to influence grape (Vitis vinifera L.) berry development and biosynthesis of phenolic compounds, and ultimately affect wine quality. Here, the accumulation and compositional changes of hydroxycinnamic acids (HCAs) and flavonoids, as well as global gene expression were analyzed in Cabernet Sauvignon grape berries under sunlight exposure treatments at diffe...

Wine grapes are usually harvested in vineyards when they ripen. However, not all of the berries in a vineyard ripen homogeneously because of different microclimates around the clusters and berries. In this study, the influence of berry heterogeneity on the phenolic content and antioxidant capacity of grapes and wines under a continental monsoon climate was evaluated for a new wine grape cultiva...
