Abstract

Cilj ovog rada bio je utvrditi promjene u prinosu i kvaliteti mošta te zastupljenost mikoriznih struktura na korijenu klonova sorte 'Škrlet', uvjetovane aplikacijom živog ektomikoriznog micelija. Pokus je postavljen 2018. godine, u vinogradu, u blizini Ivanić Grada. Mikorizno cjepivo aplicirano je na 30 trsova tri klona sorte 'Škrlet', na klonove ŠK 74, ŠK 33 i ŠK 29, a isti broj trsova svakog klona poslužio je kao kontrola. Tijekom vegetacije dva puta je napravljeno uzorkovanje korijena, pet i četrnaest mjeseci nakon primjene cjepiva, kako bi se ustanovio razvoj mikoriznih struktura na korijenu svakog klona. Uzorkovanje grožđa izvršeno je u periodu pune zrelosti. Izmjeren je prinos te prosječan broj grozdova po trsu. Također je na uzorku od deset grozdova svakog klona i njemu pripadajuće kontrole odrađena mehanička analiza grozda te osnovna kemijska analiza. Temeljen dobivenih rezultata utvrđeno je kako je mikoriza utjecala na smanjenje prinosa i prosječnog broja grozdova po trsu, što je rezultiralo povećanjem prosječne mase grozda i sadržaja šećera. Na ostale parametre osnovne kemijske analize (sadržaj ukupnih kiselina i pH) nije značajno utjecala.

Abstract (english)

The aim of this study was to determine changes in yield and quality of grape must and the presence of mycorrhizal structures at the root of the 'Škrlet' variety clones, conditioned by the application of live ectomycorrhizal mycelium. The experiment was placed in 2018, in a vineyard near Ivanić Grad. The mycorrhizal vaccine was applied to 30 vines of three 'Škrlet' variety clones, to clones ŠK 74, ŠK 33 and ŠK 29, and the same number of vines of each clone assisted as a control. During the vegetation, root sampling was done twice, five and fourteen months after the vaccine was applied, to detect the development of mycorrhizal structures at the root of each clone. Grape sampling was done at full ripeness. The yield and the average number of grape clusters per vine were measured. A grape cluster mechanical analysis and basic chemical analysis were also done on a sample of ten grape clusters of each clone and their controls. Based on the results obtained, it was determined that mycorrhiza affected the decrease in yield and average number of grape clusters per vine, which resulted in an increase in average cluster mass and sugar content. The other parameters of the basic chemical analysis (total acid content and pH) were not significantly affected.
