English. The influence of copper (Cu) on synthesis of carbohydrate content in grapevine (Vitis vinifera L.) cv. ‘Merlot’ was tested in Goriška 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.

S poskusom smo ugotavljali vpliv bakrovih spojin na sintezo ogljikovih hidratov pri vinski trti (Vitis vinifera L.) sorte 'Merlot' v vinorodnem okolišu Goriška brda v letu 2003. Poskusnemu vinogradu smo priredili bločni poskus: obravnavanje z dvokratno (IPG), večkratno (BB) aplikacijo Cu spojin in (K) brez uporabe bakrovih spojin. Vsebnost ogljikovih hidratov v listih je bila večja pri K, medtem ko v skorji enoletnega lesa pri obravnavanju BB. Pozicija lista na mladiki ne vpliva na količino ogljikovih hidratov v listih. Z aplikacijo bakrovih spojin vplivamo na slabšo kakovost grozdja, saj smo povprečno najmanjše količine ogljikovih hidratov v grozdju dobili v grozdju tretiranem z bakrovimi fungicidi.
