The agrobiological and technological value of ancient romanian grape varieties (Vitis vinifera L.) cultivated in Iaşi vineyard

Abstract

Global warming, as an extreme climatic phenomenon, shows a strong influence on vine cultivation, leading to the reconsideration of the cultivated grape varieties. The extreme heat during grapes’ maturation results in a unbalanced qualitative profile (too high sugar concentration and too low acidity concentration), losing on the way some of the wines specific for certain regions. In this article, ancient Romanian grape varieties were studied, that have been neglected in recent years and that can be reconsidered for the current conditions. The following varietieswere studied: Ardeleanca, Braghina, Cruciuliţă, Cionic, cultivated in the ampelographic collection of USAMV Iaşi. These varieties in the past were part of the old varieties of the Romanian vineyards, being cultivated before the phylloxera invasion and bringing the note of originality specific to each vineyard. Many of them have a meritorious behavior, and can be highlighted in the new zoning works of Romanian vines.
