THE INFLUENCE OF TECHNOLOGICAL FACTORS ON QUALITY INDICATORS FOR THREE VITIS VINIFERA VARIETIES CULTIVATED IN THE JIDVEI VINEYARD

Abstract

The article presents partial results of the study regarding the influence of some technological factors on the evolution of quality indicators for three Vitis vinifera L. varieties, namely Fetească Regală, Muscat Ottonel and Sauvignon Blanc. The experiments underlying the research were conducted in Jidvei’s experimental field, located in the eastern part of Alba County, on the lower course of the river Târnava Mică. The three varieties were tested under different irrigation and fertilization conditions to determine grapes’s levels of sugar, acidity and pH, which are responsible for the quality of wine production
