Comparative Data Regarding the Grapes Maturation Evolution at Feteasca Regala, Chardonnay and Pinot Noir Varieties During 2008-2010, in the Jidvei Vineyard

Abstract

The Târnave vineyard is special from the south vineyards. It includes the wines plantations from the Tarnave, Mures and Secas. The region relief is very troubled, with hills whose altitudes varies between 175 m and 544 m. The maturation as an evolutive phase is a physiological process , genetically coordinated which is characterized by morphoanathomic and chemical complex changes chimică.Physiology research undertaken (Rhodes 1980, Champagnol 1984, Fregoni 1998, Burzo 1998,) bring to attention of specialists two notions: maturation and senescence. On this line the maturation represents the physio-biochemical process by which the grapes made their quality of size, color, taste, flavor, etc., and senescence is the decline process in which essential irreversible take place that lead to damage cell ultra structure, to degradation processes, to cell death and obviously the gradual loss of quality characteristics.
