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.
The impact of water-soluble carbohydrate composition in relation to damage levels of onion thrips (Thrips tabaci Lindeman), were studied under field conditions at the Experimental Field of the ...Biotechnical Faculty in Ljubljana on 7 cabbage cultivar (Brassica oleracea L. var. capitata). Onion thrips showed weak preference on cabbage heads with high amount of total carbohydrate, fructose and glucose and higher preference on heads with high concentration of sucrose. While amount of total carbohydrate, fructose and glucose were negatively correlated with damage levels (r2 = -0.7667; r2 = -0.6947; r2 = -0.8263), sucrose amount was not. There was a strong positively relationship between sucrose amount and the level of plants infested (r2 = +0.7378). The cv."Hinova", which had the highest amount of total carbohydrate, showed itself to be the most resistant to the onion thrips.
