Enological and nutraceutical potential of some grape varieties tolerant to downy mildew and powdery mildew
AIM: Since 2012 the Veneto Region regulation (north-east Italy) allowed wine production using 20 hybrid grapevine varieties selected for their high tolerance to downy mildew and powdery mildew. Characterized by vigour, high grape productivity and low pesticide use, these varieties are suitable to develop sustainable viticulture in mountain areas located at medium altitudes.
First characterization of thiol precursors in colombard and gros manseng: comparison of two cultivation practices
AIM: Organic production of wine in the past years has known an important augmentation. This type of cultivation practice switches synthetic phytosanitary product for copper-based protection as fungicide.
Carbon isotope labeling to detect source-sink relationships in grapevines upon drought stress and re-watering
Kinetics of carbon allocation in the different plant sinks (root-shoot-fruit) competing in drought stressed and rehydrated grapevines have been investigated.
Understanding the genetic determinism of phenological and quality traits in ‘Corvina’ grape variety for selection of improved genotypes
Downy and powdery mildew are major issues in grapevine cultivation, requiring many phytosanitary treatments to ensure yield and quality. Climatic changes are also challenging grape cultivation
Influence of the agronomic management on the aroma of Riesling wines
Nitrogen fertilisation of grapevines is known to influence not only plant development and production yield, but also yeast assimilable nitrogen (YAN). This parameter is related to the growth of yeast
Effect of early defoliation on volatile composition and sensory properties of aglianico red wines
The aim of this work was to study the influence of early defoliation in the vineyard on Aglianico wines quality from Apulia region (Italy). Early defoliation was conducted in commercial Aglianico
Targeted UHPLC-QqQ-MS/MS metabolomics for phenol identification in grapevine and wine: study of a Tempranillo clone with a dark-blue berry colour
Grapevine vegetative multiplication allows the accumulation of spontaneous mutations and increase intra-cultivar genetic diversity that can be exploited to maintain grape wine quality
Sensory and chemical phenotyping of wines from a F1 grapevine population
The European Green Deal, a concept of the European Commission, aims at the reduction of pesticides in EU agriculture for 2030 by 50%. Viticulture uses the largest amounts of fungicides in the EU
Smartphone application use as a tool for water supply management
Uruguay had an average annual rainfall of 1200 mm characterized by a high monthly variability, which generates periods of water deficit and excess. The rational water management
Effect of late pruning on yield and wine composition in monastrell wines
Global warming is shifting vine phenology, resulting in a decoupling of phenolic and technological berry ripening. This is altering the balance of fruit traits, which is key relevance to winegrowers
Methyljasmonate versus nanomethyljasmonate: effect on monastrell nitrogen composition
The aim of this work was to evaluate the effect of preharvest application in Monastrell berries using two different types of applications: conventional treatments
Methyl jasmonate versus nano methyl jasmonate: effects on anthocyanins mature evolution in monastrell grapes
The climate change is afecting particulary to the South of Spain, with high temperatures. It is important to develop new strategies in order to mantain the quality of wines
Impact of electrolyzed water applied as an alternative treatment in vineyard on grape and wine quality
The main issues in viticulture are to highly decrease the use of phytochemicals. Electrolyzed water (EW) is one of the possible alternative when illness pressure is not too high
Application to grapevine leaves of different doses of urea at two phenology stage: effect on the aromatic composition of red wine
This research aimed to study the effect and efficiency of foliar application of urea on the aromatic composition of red wines elaborated from Tempranillo grapes.
From vineyard to a glass of wine: the effect of abscisic acid application on mouhtaro, a rare autochthonous variety of greece
In a context of a sustainable viticulture, a new uprising strategy to improve grape and wine composition (or quality) is the exogenous application of plant activators(Gil-Muñoz et al., 2017)
The effect of viticultural treatment on grape juice chemical composition
Viticultural management regimes influence the soil elemental profile of a vineyard, determining the microbial community distribution, insect life, and plant biochemistry and physiology
A microwave digestion ICP-MS method for grapevine bark elemental profiling
A rapid and reproducible microwave (MW)-assisted acid digestion protocol was developed to determine the elemental composition of grapevine bark samples using ICP-MS.
Exploring the effect of ripening rates on the composition of aroma and phenolic compounds in Cabernet-Sauvignon wines
The study of cultural practices to delay ripening and the characterization of their effect on wine composition is important in the mitigation of accelerated ripening caused by higher temperatures
The use of elicitors in the vineyard to mitigate the effects of climate change on wine quality
The wine sector is being directly affected by climate change. Temperatures above 30ºC can cause a lag between the ripening of the berry pulp (a rapid increase in sugar content) and the skin
Measurement of trans-membrane and trans-tissue voltages in the Shiraz berry mesocarp
In mid to late ripening, sugar and potassium (K+) accumulation into the berry slows and is eventually completed1. K+ is the most abundant cation in the berry, undertaking important physiological roles.
