A multidisciplinary approach to assess the impact of future drought scenarios on vineyard ecosystems
Drought events can strongly affect grapevine and berry physiology and subsequent wine quality, as widely demonstrated in controlled experiments.
Poster communication – Physiological responses to abiotic and biotic stress
A stratified sampling approach to investigate the impact of climate and maturity on the aroma and phenolic composition of grenache grapes and wines within the poctefa area
Context and purpose of the study. Climate change is affecting wine production and induces a large variability in wine composition between vintages.
ABA and ethephon alleviated to a different extent the impact of elevated temperatures on grape berry composition
The Intergovernmental Panel on Climate Change (IPCC) forecasts an increase in global temperature and a decrease in relative humidity (RH) in the coming decades, which may have implications for berry ripening and composition.
An effective method for extracting high-quality RNA from grapevine
Grapevine (Vitis vinifera L.) is one of the most important economic crops in the world. Because of this importance, one finds widespread molecular genetic research on this species, an important element of which is high quality RNA.
Assessing the impact of defoliation on grape volatiles profile and wine odor characteristics in four Greek red varieties (Vitis vinifera L.) using multivariate chemometrics
Context and purpose of the study. Cultivation techniques are widely recognized for their significant impact on the aroma profile of grapes and wines.
Bud fruitfulness in Vitis vinifera L. cv. Chardonnay in cool climate regions in South Africa
Bud fruitfulness is a key determinant of the potential and the actual yield. The formation of the grapevine yield spans over a period of two consecutive growing seasons (Ferrara & Mazzeo, 2023).
Can grapevine intra-varietal genetic variability be a tool for climate change adaptation? A case study at a hot and dry environment
Climate change projections point to an increase of temperatures and changes in rainfall patterns in the mediterranean region.
Climate change impacts on grapevine leafroll disease and its transmission by mealybugs
Climate change impacts crop plants, plant pathogens, and their insect vectors and hence adds abiotic stress to the triangle of plant-virus-vector interactions.
Developing effective physiological strategies to rejuvenate virus-infected vineyards by lowering the virus load in infected grapevines
Context and purpose of the study. The wine industries face significant challenges from two highly detrimental viruses: leafroll and red blotch.
Dissecting the dual role of light regarding the plasticity of grape physiology and gene regulation through daylength simulation in a semi-arid region
Context and purpose of the study. Daylength is a key climatic factor within the terroir concept. However, the complex interplay of multiple variables in regions with varying daylengths makes it challenging to isolate and investigate this specific factor.
Distribution of fungicide-resistant Botrytis cinerea mutations in the Tokaj and Eger wine regions
Botrytis cinerea is one of the most widespread host-specific fungal pathogens, causing significant yield losses and economic damage to vineyards every year.
Drought stress shapes the fungal microbiome of grapevine leaves: insights from DNA metabarcoding
Drought stress is an increasingly prevalent environmental challenge with implications for grapevine physiology and productivity, as well as for the microbiomes associated with grapevine tissues.
Effect of ozone application for low-input postharvest dehydration of wine grapes
The postharvest dehydration of grapes is a traditional practice to obtain wines with unique traits (e.g., sweet, dry/reinforced).
Effectiveness of “curettage” and rootstock over-grafting in the control of esca
Context and purpose of the study. The grapevine domestication requested the need of pruning, which expose the vines to trunk pathogens, leading to the spread of vine trunk diseases.
Effects of auxin treatment on compositional and molecular ripening dynamics in grape varieties of northern Italy
Context and purpose of the study. The temperature increase related to ongoing climate changes is causing a progressive anticipation of the ripening time, negatively affecting grape quality at harvest.
