Proceeding of the 4 rd International Symposium“NEW RESEARCH IN BIOTECHNOLOGY” USAMV Bucharest, Romania, 2011accumulation occurring in Urlati center, the difference is quite large between the center andcenter Dragasani.Merlot wine analyzed showed values of key parameters in total agreement with thecompositional quality of the grapes: the values of the alcoholic strength of acidity (total andvolatile), extract and color characteristics are higher in the center of Valea Calugareasca;values in the other two centers were different and less non-characteristic, and in 2007 wasstill one that has influenced this case the best quality wines.Table 2 – Quality parameters of wine Cabernet SauvignonQuality parameters of wine /Parametrii de calitate ai vinuriloralcoholic strength,vol% alcohol /tariaalcoolicatotal acidity, g/ltartaric acid/aciditatetotaladry extract g/l /extractsecvolatile acidity, mg/lCH 3 COOH/ aciditateavolatilavineyard ecosystem I, 2007 12,0 5,4 26,4 0,4vineyard ecosystem I, 2008 11,6 5,6 26,2 0,2vineyard ecosystem I, 2009 11,0 6,1 26,0 0,3vineyard ecosystem II, 2007 12,4 6,1 32,0 0,3vineyard ecosystem II, 2008 12,0 6,5 31,7 0,3vineyard ecosystem II, 2009 11,7 6,7 30,3 0,4vineyard ecosystem III, 2007 13,3 5,8 33,0 0,4vineyard ecosystem III, 2008 12,7 6,0 31,7 0,3vineyard ecosystem III, 2009 12,0 6,5 30,5 0,5Table 3 - Quality parameters of wine MerlotQuality parameters of wine /Parametrii de calitate ai vinuriloralcoholic strength,vol% alcohol /tariaalcoolicatotal acidity, g/ltartaric acid/aciditatetotaladry extract g/l/extract secalcoholic strength,vol% alcohol /tariaalcoolicavineyard ecosystem I, 2007 12,4 5,8 25,5 0,4vineyard ecosystem I, 2008 11,0 6,0 24,0 0,4vineyard ecosystem I, 2009 11,0 6,1 24,8 0,3vineyard ecosystem II, 2007 13,2 5,2 30,3 0,4vineyard ecosystem II, 2008 13,0 5,3 30,2 0,2vineyard ecosystem II, 2009 12,1 5,5 30,0 0,4vineyard ecosystem III, 2007 12,7 5,1 27,0 0,5vineyard ecosystem III, 2008 12,4 5,5 27,3 0,3vineyard ecosystem III, 2009 11,3 5,9 25,0 0,3120

CONCLUSIONS1. The quality of grapes and wines is a result of a multifactorial system, winevariety is always lying in close interdependence with ecological and geographicalconditions, with its specific biotope and ecosystem;121
