ECOPHYSIOLOGICAL DESCRIPTION OF SITES AND WINE SENSORY PROPERTIES AS A TOOL FOR ZONING IN VITICULTURE
All the vineyards were cultivated with cv. Chardonnay and managed according to standardized techniques.
Throughout the summer the following ecophysiological measures were done: Vapour Pressure Deficit, Sun Radiation, Leaf Irradiance, Leaf Temperature, Leaf Water Potential, and Chlorophyll Fluorescence emission.
At the end of vegetative growth Whole Plant Leaf Area (WPLA) was estimated.
The six landscape units used for these observations showed different ecophysiological characteristics, in respect of Plant Available Water, Leaf Irradiance, Electron Transport Rate, and Whole Plant Leaf Area-Yield ratio.
WPLA, crop level and juice quality parameters were correlated to wine sensory properties.
In the zoning approach to optimize vineyard performance, information about soil traits is linked to data about micro-climatic conditions.
This information may be successfully managed by vine growers in order to modify the crop to specific enological aims.
Wine quality is viewed as the outcome of a complex set of interactions that involve the most important factors that define the environment.
