Importanza del monitoraggio micro-meteorologico nella caratterizzazione del terroir

Abstract

[English version below]

Le variabili meteorologiche e micro-meteorologiche ricoprono un importante ruolo sulla risposta vegeto-produttiva della vite e di conseguenza sulla qualità delle produzioni. Utilizzando una rete wireless di sensori sono stati monitorati i parametri meteorologici e micro-meteorologici di 4 vigneti del territorio toscano e in differenti condizioni di gestione agronomica. La comparazione di Land Indicators (indici calcolati a partire dal dato meteo territoriale proveniente da una stazione meteo tradizionale situata al di fuori del vigneto) e Proximity Indicator (indici calcolati dal dato meteo prossimale rilevato all’interno del vigneto) fa emergere come le due scale di indagine offrano una caratterizzazione del terroir significativamente diversa, in particolare per quanto concerne il ciclo giornaliero della temperatura del grappolo. Lo studio dell’impatto delle diverse pratiche di gestione della chioma sul micro-clima, ha evidenziato differenze tra le tesi defogliate e non, soprattutto nei valori di temperature massime e radiazione misurate a livello del grappolo. Questo studio evidenzia come il monitoraggio micro-meteorologico sia uno strumento efficace per ottenere delle sotto-zonazioni dei vigneti soprattutto in territori caratterizzati da morfologia eterogenea e quindi da grande variabilità spaziale dei parametri ambientali.

The micro-meteorological and meteorological variables play an important role on the vegetative-productive response of the grapevine and consequently on quality products. Using a wireless sensor network, meteorological and micro-meteorological parameters of four Tuscany vineyards have been monitored and in different conditions of agronomic management. The comparison of Land Indicators (territorial data from a traditional weather station located outside the vineyard) and Proximity Indicators (proximal data monitored inside the vineyard) highlighted large differences especially with regard to the diurnal course of bunch temperature. The impact of different management practices on canopy microclimate pointed out significative differences between defoliated and non-thesis, especially in maximum temperature and solar radiation at bunch level. Present study emphasize the role of micro-meteorological monitoring in providing a reliable picture of vineyard sub-zones that can be useful in those areas characterized by an heterogeneous morphology and hence by a large spatial variability of environmental parameters.

Image based vineyard yield prediction using empirical models to estimate bunch occlusion by leaves

Vineyard yield estimation brings several advantages to the entire wine industry. It can provide useful information to support decision making regarding bunch thinning practices, harvest logistics and marketing strategies, as well as to manage stored wine and cellar tanks allocation. Today, this estimation is performed mainly using manual methods based on destructive bunch sampling.

Impact of nitrogen addition timing on the synthesis of fermentative aromas in alcoholic fermentation

Among the different compounds present in the must, nitrogen is an essential nutrient for the management of the fermentation kinetics but it also plays an important role in the synthesis of fermentative aromas.

Study of Spanish wine sensory analysis data over a 3-year period

This study presents an investigation based on sensory analysis data of Spanish wines with geographical indications collected over a three-year period. Sensory analysis plays a crucial role in assessing the quality, characteristics, and perception of wines. The trained tasting panel at Dolmar Laboratory, accredited for objective sensory evaluation of wines since 2016, has been tasting over 5000 wines. However, it is since 2021, when a computer application for tastings was developed, that the digitalization of data allows for detailed statistical analysis of the results.

USDA national grapevine germplasm resources: new curators, new directions

The National Plant Germplasm System (NPGS) in the United States Department of Agriculture safeguards numerous species. Grapevines are split in two locations: Davis, CA and Geneva, NY. The two germplasms maintain 43 Vitis species with over 4500 genetically unique accessions.

Diversity of arbuscular mycorrhizal fungi on grapevine roots across an edaphoclimatic gradient

Challenges associated with climate change, such as soil erosion and drought, have impacted viticulture across wine regions globally in recent decades. As winegrowers struggle to maintain yield and quality standards under these conditions, methods to adapt to and mitigate the impacts of climate change have become more prevalent. One potential mitigation strategy is to enhance symbiotic interaction of grapevine roots with arbuscular mycorrhizal fungi (AMF).
