Abstract	Ovaj diplomski rad bavi se istraživanjem utjecaja ektomikorize na korijenu vinove loze na mehanički i kemijski sastav grožđa. Mikorizni preparat apliciran je 2012. godine na 40 trsova Traminca crvenog na Vinogradarsko-vinarskom pokušalištu Jazbina koje se nalazi u sklopu Zavoda za vinogradarstvo i vinarstvo Agronomskog fakulteta u Zagrebu, a istraživanje je provedeno u 2014. godini. Uvometrijom i mehaničkom analizom utvrđena je prosječna masa grozda, prosječni broj bobica po grozdu, prosječna masa bobice, prosječan broj grozdova po trsu, prosječan prinos po trsu, te udio mesa, kožice i sjemenke u bobici. Kemijskim analizama utvrđen je sadržaj šećera, ukupna kiselost, pH vrijednost, koncentracija pojedinačnih organskih kiselina te aromatski profil grožđa. Dobiveni rezultati pokazali su da mikoriza utječe na povećanje prosječnog broja bobica po grozdu, na smanjenje prosječne mase bobice, na povećanje prosječnog broja grozdova po trsu, na povećanje prosječnog prinosa po trsu, na smanjenje udjela kožice i povećanje udjela sjemenke u bobici. Osim na mehanički, mikoriza je utjecala i na kemijski sastav smanjenjem sadržaja šećera, povećanjem ukupne kiselosti, smanjenjem pH vrijednosti, povećanjem koncentracije vinske i jabučne kiseline, te smanjenjem koncentracije aromatskog spoja α-terpineola.
Abstract (english)	This master's thesis deals with influence of ectomycorrhiza on root system of grapevine on mechanical and chemical composition of grapes. Mycorrhizal inoculum was applied in the year of 2012 on 40 vines of Traminer grown on viticulture-wine experimental field Jazbina, which is part of the Department of viticulture and enology of Faculty of Agriculture, University of Zagreb. Research was conducted in 2014. Average cluster weight, average berry number per cluster, average berry weight, average cluster number per vine, average yield per vine and percentage of meat, skin and seed in berry were determined by mechanical analysis. Soluble solids, titratable acidity, pH, organic acid concentration and aromatic profile were determined by chemical analysis. Results showed that mycorrhiza affects on increased average berry number per cluster, decreased average berry weight, increased average cluster number per vine, increased average yield per vine, decreased percentage of skin in berry and increased percentage of seed in berry. Mychorrhiza also affected chemical composition by decreasing sugar content, increasing total acidity, decreasing pH, increasing concentration of tartaric and malic acid and decreasing concentration of aromatic compound alpha terpineol.
