IMPACT OF CLIMATE FACTORS ON YIELD AND QUALITY OF VINE VARIETY CABERNET SAUVIGNON IN PODGORICA WINE GROWING REGION

The influence of climatic factors on grape yield, grape cluster weight, sugar and acidity content in stum in variety Cabernet Sauvignon was measured in period from 2011 to 2013 at the experimental field of Biotechnical Faculty in Podgorica. The study was conducted in the vineyard of the Biotechnical Faculty in Podgorica in the stage of full grape maturity. The highest grape yield as well as the cluster weight were measured in 2012 (1.2 kg/m^2 and 125 g respectively), while the lowest values were measured in 2013 - 0.88 kg/m^2 and 92 g. Highest sugar content in stum was measured in 2011, and lowest in 2013. The highest acid content was measured in 2013 (6.50 g/l) as a result of heavy rainfall during the growing season, especially in August and September. Differences between the studied parameters were statistically significant. The results showed that the yield and quality of grapes were in direct relation with the weather conditions in certain years of experiments.
