| Popis: | In evaluating the quality of the viticultural terroir there are use different quality parameters. The exposed leaf area (SFE) curently considered an indicator better than planting density to be used as a quality factor in the AOC regulations. Getting a projected yield, in terms of quality and quantity, it can be achieved only by limiting the vegetative growth at a certain level to stimulate the fructification, but under the conditions of maintaining a photosynthetic activities to satisfy the metabolic needs of grapes (SFE/kg grapes). Exposed Leaf Area/production is an indicator that allows keeping under control the quality of grape production. The optimal value of this index is specific to the variety and viticultural terroir. Under the ecopedoclimatic conditions of the area DOC Dealu Mare-Valea Calugareasca the maximum sugars potential of carbohydrate metabolism, determined by the correlation analysis, was achieved as the SFE/P 1.85 sqm/kg at Riesling italian, 1.41 sqm/kg at Feteasca regala, 1.85 sqm/kg at Merlot, 1.78 sqm/kg at Cabernet Sauvignon and 1.83 sqm/kg at Burgund mare.  SFE/P correlation is specific to each viticultural terroir. The alcoholic potential of wine color intensity were strength correlated with the SFE/P raport. The optimal values of the SFE/kg report, identified at the varieties studied, underlying the differentiated technologies for viticulture in the area DOC Dealu Mare Valea Calugareasca |
