Abstract

Cilj ovog istraživanja je ustanoviti na koji način primjena živog ektomikoriznog micelija na korijen vinove loze, utječe na mehanički i kemijski sastav grožđa kultivara Syrah (Vitis vinifera L.). Cjepivo je aplicirano na 40 trsova 2013. godine na Vinogradarsko – vinarskom pokušalištu u Jazbini. Ovim istraživanjem analiziran je sadržaj šećera, ukupna kiselost, pH, sadržaj antocijana, flavonola, flavanola u grožđu. Dobiveni rezultati pokazali su da je mikoriza pozitivno utjecala na većinu parametara, kao što su na prinos po trsu i masu grozda. Isto tako je utjecala na povećanje ukupnih kiselina, te fenolnog sastava ali i na smanjenje pH.

Abstract (english)

The objective of this study was to determine how the application of living ectomycorrhizal mycelium on the vine root affected the mechanical and chemical structure of grape cultivar Syrah (Vitis vinifera L.). Ectomycorrhiza was applied to 40 vines at the experimental station in Jazbina in the year of 2013. This study analysed the content of sugar, total acidity, pH, content of anthocyanins, flavonols, and flavanols in grapes. The results obtained showed that mycorrhiza had a positive effect on most parameters, such as yield per vine and cluster weight. It also influenced the increase total acidity, as well as phenolic composition, but also on the reduction of pH.
