Valutazione dell’equilibrio vegeto-produttivo con metodiche di proximal sensing

Abstract

Nel biennio 2008-2009, nell’ambito di un progetto multidisciplinare coordinato e finanziato dal Consorzio Tuscania, 4 vigneti in differenti zone della Toscana sono stati monitorati con strumenti di proximal sensing al fine di valutare la variabilità riscontrabile e ottenere delle indicazioni sulle risposte vegetative delle piante e quanti-qualitative delle produzioni. La creazione di mappe di NDVI (uno degli indici di vegetazione più comunemente utilizzati) e di spessore delle chiome (CT, derivato dalla lettura dei sensori ad ultrasuoni), ha permesso di evidenziare nette differenze tra i vigneti studiati e all’interno dei singoli appezzamenti, oltre ad una forte influenza temporale sulle caratteristiche delle chiome; tali evidenze sono state confermate da un’analisi della varianza multivariata. I dati rilevati sono stati correlati con alcuni indici comunemente utilizzati per la valutazione vegeto-produttiva delle piante ottenendo delle correlazioni significative, a conferma della validità dei rilievi effettuati e del loro possibile utilizzo come metodo di monitoraggio della situazione esistente in vigneto e di supporto nei processi decisionali

English version: In 2008, collaborating with Tuscania Consortium, Ibimet of Florence and IASMA, a research was started with the aim of understanding and monitoring existing variability in vineyards and, basing on it, evaluating agronomical practices useful for qualitative and quantitative responses optimization. With this purpose, some experimental parcels were chosen in 4 different Sangiovese and Cabernet S. vineyards placed in 3 areas of Tuscany. Parcels were made by the use of different canopy management techniques in various vigour zones. In established periods (fruit setting, veraison and before technological maturity) some instrumental records were made, using ATV mounted optical and ultrasonic sensors; at the same time, indirect measurements of leaf surface and a Point Quadrat were performed. Statistical analysis allowed to validate instrumental relives and to underline the capability of the system of surveying both spatial and temporal variability both an artificial one, made by agronomical practices.

Climate change and viticulture in Nordic Countries and the Helsinki area

The first vineyards in Northern Europe were in Denmark in the 15th century, in the southern parts of Sweden and Finland in the 18th century at 55–60 degrees latitude. The grapes grown there have not been made into wine, but the grapes have been eaten at festive tables. The resurgence of viticulture has started with global warming, and currently the total area of viticulture in the Nordic countries, including Norway, is estimated to be 400–500 hectares, most of which is in Denmark. Southern Finland, like all southern parts of Northern Europe, belongs to the cool-cold winegrowing area.

Rare earth elements in grapes and soil: study of different soil extraction methods

Lanthanides, together with scandium and yttrium, make up the group of Rare Earth Elements (REEs). An official method for analysis of the bioavailable REEs accumulated by plants, depending mainly on soil characteristics, chemical speciation in soil and the specific ability of the plant, is still lacking.

Deciphering the color of rosé wines using polyphenol targeted metabolomics

The color of rosés wines is extremely diverse and a key element in their marketing. It is due to the presence of red anthocyanins extracted from grape skins and pigments formed from them and other wine constituents during wine-making.
