The influence of copper (Cu) on synthesis of carbohydrate content in grapevine (Vitis vinifera L.) cv. 'Merlot' was tested in Goriska brda winegrowing district. In 2003 three different treatments with Cu-compounds were applied as follows: IPG (integrated control with 1 Cu treatment), BB (with several Cu treatments) and K (no Cu treatment). The carbohydrate content was higher in vine leaves with no Cu treatment, but also in shoot bark of vines with BB treatment. The leaf position on the shoot tip has not influence on carbohydrate content in leaves. Carbohydrate content in grape was lower in grape treated with Cu fungicide.
