Recent investigations confirm that different levels of nutritional availability, deriving from by fertilization practices or the intrinsic composition of the soil (terroir) can affect grape quality.
The project intends to exploit GC-MS techniques in order to:
- Identify the most appropriate tools and define the experimental protocols for analysing the physiology and mechanisms for nutrient uptake by vine roots, using stable isotopes of elements such as N, Fe, Mg and B as tracers;
- Study the effects of mineral (NO3- and NH4+) and organic (urea) forms of nitrogen on vine development , gene expression and grape quality;
- Analyse how pedo-climatic-terroir can affect gene expression during the ripening process and consequently, the aroma of grapes and wine produced by varieties that are typical of the Verona region.
