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.

Evaluation of spraying effects of plant protection unmanned aerial vehicle on two different training systems of vine in Northeast China

In recent years, the application of plant protection unmanned aerial vehicle (UAV) in agricultural pest control has become more and more popular. However, there are few reports about the application of plant protection UAV for wine grapes, and there are no studies comparing the spraying effect of plant protection UAV with that of manual operation in vineyards. In this context, the objective of this study was to explore the feasibility of using plant protection UAV in vineyards instead of manual operations by evaluating the effectiveness of UAV spray in two common grape training systems in Northeast China.

Enhancing the color traits of ‘Nebbiolo’ and ‘Dolcetto’ grapes: the role of abscisic acid during ripening

The red Italian variety Nebbiolo (Vitis vinifera L.), used in the production of the prestigious Barolo and Barbaresco wines, is renowned for its aromatic and structural complexity but also for its low color intensity.

Anthocyanin profile is differentially affected by high temperature, elevated CO2 and water deficit in Tempranillo (Vitis vinifera L.) clones

Anthocyanin potential of grape berries is an important quality factor in wine production. Anthocyanin concentration and profile differ among varieties but it also depends on the environmental conditions, which are expected to be greatly modified by climate change in the future. These modifications may significantly modify the biochemical composition of berries at harvest, and thus wine typicity. Among the diverse approaches proposed to reduce the potential negative effects that climate change may have on grape quality, genetic diversity among clones can represent a source of potential candidates to select better adapted plant material for future climatic conditions. The effects of individual and combined factors associated to climate change (increase of temperature, rise of air CO2 concentration and water deficit) on the anthocyanin profile of different clones of Tempranillo that differ in the length of their reproductive cycle were studied. The aim was to highlight those clones more adapted to maintain specific Tempranillo typicity in the future. Fruit-bearing cuttings were grown in controlled conditions under two temperatures (ambient temperature versus ambient temperature + 4ºC), two CO2 levels (400 ppm versus 700 ppm) and two water regimes (well-watered versus water deficit), both in combination or independently, in order to simulate future climate change scenarios. Elevated temperature increased anthocyanin acylation, whereas elevated CO2 and water deficit favoured the accumulation of malvidin derivatives, as well as the acylation and tri-hydroxylation level of anthocyanins. Although the changes in anthocyanin profile observed followed a common pattern among clones, such impact of environmental conditions was especially noticeable in one of the most widely distributed Tempranillo clones, the accession RJ43.
