Physiological response to drought and heat stress in the leaves of table grape varieties
Increasingly pronounced climate changes, including prolonged drought periods, pose a significant challenge to the cultivation of table grape varieties.
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.
The drought, the temperature, and the time: drivers of osmotic adjustment?
Context and purpose of the study. Leaf osmotic adjustment (i.e., active accumulation of osmolytes in the cells) has been reported in grapevines in response to drought and as a natural process throughout the growing season (seasonal osmotic adjustment).
Phylloxera root infection drives vineyard water
Most of the rootstocks used in viticulture today are partly resistant against grape phylloxera (Daktulosphaira vitifoliae Fitch) and host phylloxera on the root system without conspicuous negative impacts on fruit production).
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.
Pedicel lenticel diversity of cultivars and their influence on cell death and berry shrivel
Shrinking berries are the common symptoms of Berry Shrivel (BS) and Late-Season-Dehydration (LSD) in grapevine cultivars.
Influence of thermal stress on Malbec, Syrah, and Bonarda (Vitis vinifera L.) anthocyanin content and evolution in growing seasons with heatwaves in semi-arid climate (Argentina)
It is known that high temperature influences the synthesis, transformation and degradation of grape anthocyanin (ANT) threatening the quality of grapes and coloured wines.
Ethanol reduces grapevine water consumption by limiting transpiration
Studies suggest that ethanol (EtOH), triggers plant adaptation to various stresses at low concentrations (10 µM to 10 mM).
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.
Grapevine under nutrient stress: exploring the adaptive mechanisms in response to iron deficiency conditions
In plants, stress due to nutrient deficiency can significantly impair their development and productivity.
Guard cell metabolism – A key for regulating drought resilience?
In view of increasing drought frequencies due to climate change, enhancing grapevine resilience to water scarcity has become vital for sustainable viticulture.
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.
Grapevine Shiraz disease-associated viruses lead to yield losses by altering transcription of genes
Context and Purpose of Study. Grapevine Shiraz disease (SD), which is associated with Grapevine Virus A (GVA), is one of the highly destructive diseases affecting Australian and South African vineyards.
isUP-AgrO European project – unlocking the potential for agricultural research on an EU outmost region: boosting ISOPlexis center
The isUP-AgrO project aims to enhance the capability of ISOPlexis – Centre of Sustainable Agriculture and Food Technology, a research unit from the University of Madeira, an outermost region of Portugal.
The impacts of simulated heatwaves on the induction and maintenance of bud cold tolerance in cultivated and wild-type Vitis species
Low temperatures are required for the acquisition and maintenance of bud cold tolerance, which are necessary for grapevines to survive freezing temperatures in winter.
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.
Strigolactones as possible elicitors in sunburn defense mechanisms in grapes: preliminary results
Due to altered climatic conditions, grape berry sunburn has become one of the main challenges in contemporary viticulture.
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.
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.
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.
