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.

Innovations on red winemaking process by ultrasound technology

High power ultrasound has been recently recognized one of the most promising technologies in winemaking processes, especially after the recent OIV resolution, concerning the application of ultrasounds on crushed grapes to promote the extraction of skin compounds.

Soil variability effects on vine rootzones and available water

Aim: The aim of this work is educating people about soil variability, vine rootzone depth and readily available water holding capacity. The concept of terroir is readily discussed in the wine industry but many people involved are unable to describe a soil profile and interpret its limitations that impact on vine growth, fruit quality and wine produced. This paper discusses soil physical characteristics important to vine root growth and readily available water holding capacity (RAW).

Weather classification over the Western Cape (February, 1996 – 2000) and viticultural implications in the Stellenbosch wine district

Une étude préliminaire des situations météorologiques journalières a été réalisée pour l’Afrique du Sud et pour les mois de février (période de maturation des raisins dans la Province occidentale du Cap), à l’image de la classification synoptique réalisée aux latitudes tempérées en France (Jones & Davis, 2000), afin d’étudier les relations entre le climat et la viticulture à des latitudes plus basses.

AROMA AND SENSORY CHARACTERIZATION OF XINOMAVRO RED WINES FROM DIFFERENT GREEK PROTECTED DESIGNATIONS OF ORIGIN, EFFECT OF TERROIR CHARACTERISTICS

The quality of wines has often been associated with their geographical area of production. The aim of this work was to characterize Protected Designation of Origin (PDO) Xinomavro red wines from different geographical areas of Amyndeon and Naoussa in Northern Greece, elaborated with variables that contribute to their differentiation, such as soil characteristics, altitude, monthly average temperature and rainfall.
Xinomavro fruit parcels from different vineyards within the two PDO zones (5 PDO Naoussa and 6 PDO Amyndeon) were vinified following a standard winemaking process. A total of 25 aroma compounds were quantified using gas chromatography-mass spectrometry (GC-MS) with simultaneous full scan and selected ion monitoring for data recording, and odor activity values (OAVs) were determined.

The Australian geographical indication process

The first white settlers arrived in Australia in 1788 and brought grape vine cuttings with them. As migration to Australia continued to grow during the XIX Century more and more vine cuttings, viticulturists and winemakers from Britain, France, Germany, ltaly, Switzerland and Yugoslavia founded their businesses.
