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.

Juvenile-to-adult vegetative phase transition in grapevine 

The sequential activity of miR156 and miR172 controls the juvenile to adult phase transition in many plant species, where miR156 abundance decreases while miR172 increases along plant development. Very little is known about phase transition in horticultural woody species, which show substantially long vegetative phases. In grapevine, phase transition seems to be dissociated, displaying a first transition from juvenile to adult vegetative state in the first year, coincident with tendril differentiation and a subsequent induction of inflorescences in place of some of tendrils in later years under flowering inductive environmental conditions. Since grapevine is a highly heterozygous species, the generation of genetically homogeneous material for replicated transcriptomic analyses from seed-derived plants was a main challenge.
