content, A-acidity content) to the optimalvalues of each variety P opt, Z opt , A opt. Optimalvalues in Dealu Mare vineyard – ValeaCalugareasca are the multi-annual averages ofthese values (Pârcalabu, 2010), as follows:sugar – 210 g/l, acidity-4,4 g/l of tartric acid,production – 2,62 kg/vine. Therefore they aredefined: Production quality coefficient: c pdefined by the ecuation: c p = P/P opt ; Qualitycoefficient in sugar must content: c z defined bythe ecuation: c z = Z/Z opt ; Quality coefficient inmust total acidity content c a defined by theecuation: c a = A/A opt . Quality vector has in thiscase, the component c = ( c p, c z, c a ) . The bestquality is considered when, on each componentquality coefficient exist and has the value closeto 1. This being the ideal case, c = (1, 1, 1) or ifthey are expressed in percentages then thisquality will become c = (100%, 100%100%).In this case the values of quality coefficientsare sub-unitary or supra-unitary, we canconclude that, qualitatively speaking, theculture is not at optimal parameters.ExperimentalvaluesCabarnetSauvignon(fertilized)CabarnetSauvignon(control)Small-berry grape only formats13.06.2012Tecnophyt PK 3 l/ha(Potassium phosphate)Total Phosphorus P 2 O 5 30% w/w,Total PotassiumK 2 O 20% w/w, pH 4;Table 2.

Appreciating thequality potential of a variety in accordance tothe relative quality coefficient is made takinginto consideration the fact that the variety has agreater adaptability area as the relative qualitycoefficient values recorded are closer to zero.Table 3.
