Abstract

The aim of this study was to assess the influence of application of mycorrhizal fungal inoculum on the Portugieser wine chemical composition. The experiment was conducted in fall 2016. in 3 locations in the area of ZOI Plešivica, with the „Mykoflor” vaccine of Bio-budućnost d.o.o company application. The vaccine was applied to 100 vines of Portugieser variety, with the same number of untreated vines as a control. Chemical composition analysis of wine, as well sensory evaluation was carried out after the harvest in 2018. The results obtained demonstrated the positive impact of mycorrhiza on the wine chemical composition as an increase in total acidity, individual organic acids, wine ash, as well as decrease in pH value. Mycorrhiza also had a positive effect on the wine polyphenolic composition and sensory evaluation.
