Influence of Meteorological Factors on the Quality of 'Pinot Noir' Grapevine Grown in Two Wine-Growing Regions in Serbia

Abstract

The aim of this study was to analyze the effect of meteorological factors on the quality of 'Pinot Noir' grapes in two wine-growing regions in Serbia: Sumadia-Great Morava (locality Radmilovac - Faculty of Agriculture, Belgrade) and Banat (locality Vrsac - 'Vrsac Vineyards') in the period 2009-2011. Based on the climate conditions recorded in the multi-annual period (1982-2011), which were the comparison basis for the investigation years, climatic characteristics of the studied sites were determined. There were differences among the meteorological factors in the regions (air temperature, average start and end of the growing season, length of growing season and precipitation). The mechanical properties of bunch and berry (bunch length, width and mass, berry and stem mass), and quality properties of grapes (sugar content, total acid content in the must, total phenol content and antioxidant activity), were analyzed for vines from both wine-growing regions. These indicators of climate elements for different growing regions resulted in the production and qualitative characteristics of 'Pinot Noir' grapes.
