The popularity, the qualitative parameters and the impressive variability proved by the Cabernet Sauvignon variety, offers new ways of approach to the practice of winery and to scientific research. This paper presents a comparative study regarding the influence of some biostimulators on the production and quality potential of the Cabernet Sauvignon variety, in the ecological, pedological and climatic conditions recorded in Urlati wine center, from Dealu Mare vineyard. The experiment proved the application of 3 treatments with these bio-stimulators (Tecnophyt PK, Tecamin BRIX, Tecnokel amino CAB 2), during grape phonological growth, as follows: at the binding of the grapes (berry) 1-2 mm, when the grapes had a diameter of 4-6 mm and when the grapes had 6-8 mm. Observations and detailed determinations regarding the agro-biological and technological behavior were performed in the same time, but the production was especially evaluated in terms of physical-chemical parameters of the grapes, in order to obtain some quality wines, with particular notes. All the obtained results in terms of production, quantity and quality are leading to the idea that the used biostimulator substances had a positive influence, with the remark that for a 5.8% production increase, the quality parameters (sugar, acidity, polyphenols) are situated in the same limits, even higher sometimes, fully justifying their use.
