SUMMARY Phenological models are considered key tools for the short-term planning of viticultural activities and long-term impact assessment of climate change. In the present study, statistical phenological models were developed for budburst (BUD), flowering (FLO) and veraison (VER) of 16 grapevine varieties (autochthonous and international) from the Portuguese wine-making regions of Douro, Lisbon and Vinhos Verdes. For model calibration, monthly averages of daily minimum (Tmin), maximum (Tmax… 

Phenological forecasting models and pollen quality of Vitis vinifera L.

The phenological models developed in this study presented high accuracy when applied to several cultivars in different regions and can be used as a predictor tool of budburst and flowering in Portugal.

Grapevine Phenology of cv. Touriga Franca and Touriga Nacional in the Douro Wine Region: Modelling and Climate Change Projections

The results establish grounds for the implementation of a decision support system for monitoring and short-term prediction of grapevine phenology, thus promoting a more efficient viticulture.

Multifactor Models for Improved Prediction of Phenological Timing in Cold-climate Wine Grapes

An accurate predictive model for estimating the timing of seasonal phenological stages of grape (Vitis L.) would be a valuable tool for crop management. Currently the most used index for predicting

Climate change impacts on viticulture in Croatia: Viticultural zoning and future potential

Since changes in temperature and precipitation have different effects on (a) all developmental stages of grapevines in most of the wine regions worldwide (i.e., on their phenological characteristics)

Modelling the phenological development of cv. Touriga Nacional and Encruzado in the Dão Wine Region, Portugal

The grapevine vegetative cycle, which is morphologically described by its phenological stages, is strongly determined by weather conditions. Phenological models are widely applied in viticulture and

Relationships between Cabernet Sauvignon phenology and climate in two Spanish viticultural regions: observations and predicted future changes

Abstract The aim of the current research is to analyse potential changes in the phenology of Cabernet Sauvignon under future climate change scenarios. The study compares results from two areas with

Phenological Model to Predict Budbreak and Flowering Dates of Four Vitis vinifera L. Cultivars Cultivated in DO. Ribeiro (North-West Spain)

Assessment of the thermal requirements of the most important grapevine varieties in northwestern Spain to better understand the impact of climate change on their phenology allowed obtaining a global prediction model that can adequately predict budburst and flowering dates for all varieties.

Climate change impacts on phenology and ripening of cv. Touriga Nacional in the Dão wine region, Portugal

The present study is devoted to climate change impact assessment on the phenological development and ripening of cv. Touriga Nacional in the Dão Wine Region, Portugal. For this purpose, the dates of

Phenology of Tempranillo and Cabernet-Sauvignon varieties cultivated in the Ribera del Duero DO: observed variability and predictions under climate change scenarios

Aim: This research examined relationships between grapevine phenology and climate in the Ribera del Duero DO (Spain). The observed varieties included Tempranillo, the main variety planted in the



Increasing the robustness of phenological models for Vitis vinifera cv. Chardonnay

Model performance was especially high for the prediction of flowering and veraison, and comparison with other models confirmed it as a better predictor of phenology, even in extremely warm years.

Analysis of the relationships between climate variability and grapevine phenology in the Nobile di Montepulciano wine production area

SUMMARY Climate represents one of the main inputs necessary for plants to complete their vegetative–productive cycle, having a direct effect on the onset and duration of phenological stages and

Winegrape phenology and temperature relationships in the Lisbon wine region, Portugal

Aim: To investigate the characteristics, relationships and trends in the phenology of four winegrape varieties and associated temperature relationships in the Lisbon wine region (LWR), between 1990

Projecting the impacts of climate change on the phenology of grapevine in a mountain area

Background and Aims:  The strong link between climate and grapevine phenology suggests a potentially stronger impact of climate change on viticulture in climate-limited areas, including mountain

Modeling Phenology, Water Status, and Yield Components of Three Portuguese Grapevines Using the STICS Crop Model

Viticulture plays a key role in Portuguese economic growth. The possibility of obtaining early predictions of viticultural parameters, such as phenology, water status, yield, and potential wine

Grapevine Phenology and Climate Change: Relationships and Trends in the Veneto Region of Italy for 1964–2009

A long-term (1964–2009), multiple Vitis vinifera L. cultivar data set has provided a comprehensive assessment of cultivar similarities/differences in phenological timing and growth phases and

General phenological model to characterise the timing of flowering and veraison of Vitis vinifera L.

A general phenological model, GFV, has been successfully developed to characterise the timing of flowering and veraison for the grapevine and can be used as an easy predictor of phenology for different varieties under climate change scenarios.

The challenge of adapting grapevine varieties to climate change.

Climate change is expected to advance grapevine phenological stages. After the cali- bration and the validation of a degree-days model, we were able to accurately simulate dates of bud- break,

Climate Influences on Grapevine Phenology, Grape Composition, and Wine Production and Quality for Bordeaux, France

By variety, the relationships between phenology, climate, and composition were typically higher for Merlot than for Cabernet Sauvignon and could be an indication that, in Bordeaux, Merlot is more phenologically and climatologically sensitive.

Climate change scenarios applied to viticultural zoning in Europe

Climate is one of the main factors controlling winegrape production. Bioclimatic indices describing the suitability of a particular region for wine production are a widely used zoning tool. Seven
