Studies on the influence of the load charged on the technological potential of red cultivated vineyards in the wine center of Iaşi Copou

Abstract

The quantity and quality of the grape production depends on the biological potential of the varieties, the favorability of climatic conditions and the eye loads left to be cut. Achieving quality production with healthy grapes, high sugar concentrations and high phenolic content is a priority for viticulturists. In order to determine the influence of the fruit load attributed to cutting on the technological potential of the red varieties cultivated in the Copou Iaşi vineyard, the varieties Arcaş and Cabernet Sauvignon were studied. Three loads were tested: 20 eyes / bud (T1),36 eyes / bud (T2) and 28 eyes / bud (M). The T1 variant was highlighted with reduced eye load, which positively influenced the size of the grapes, the accumulations of sugars and the phenolic compound content.
