Comparative Researches Regarding the Behavior of Some Wine Grape Varieties Cultivated in Different Areas of Transylvania
AbstractThe aim of this paper was to determine the behavior of some wine grape varieties regarding the variations of: fertility, yield and water consumption of vine in two different areas of Transylvania (Blaj wine-growing center and Cluj Napoca). Wine grape varieties taken for study are ‘Fetească regală’, ‘Riesling italian’ and ‘Muscat Ottonel’. Vines water consumption has been established, using water balance method in soil. Generally in Cluj-Napoca, where climatic conditions for cultivation of vines are less favorable than in the wine-growing center Blaj, have being obtained lower values to all parameters at all varieties, less the water consumption which is higher in Cluj Napoca, due to abundant rainfall. Correlation between real evapotranspiration (RET) and grape production is linear, distinctly significant, indicating a strong dependence of grape production with water consumption of vine.
