Abstract:Poskus je potekal leta 2018 in smo ga izvedli v Hercegovščaku pri Gornji Radgoni, na sorti 'Chardonnay'. Namen naloge je bil preveriti ali lahko z višino listne stene in zelenimi deli v vinogradu vplivamo na zmanjšanje negativnih vplivov klimatskih sprememb na letni razvoj vinske trte, s tem reguliramo čas trgatve in vplivamo tudi na kakovost vina, primernega za pridelavo penin. Rezultati kažejo, da z regulacijo listne površine v veliki meri vplivamo na parametre kakovosti grozdja in vina. Z vršičkanjem vplivamo na čas dozorevanja grozdja in trajanje razvojnih faz vinske trte. Nizko vršičkanje (nad drugo žico) je vplivalo na kasnejše in počasnejše dozorevanje grozdja. Na dan trgatve je bila pri tem obravnavanju v grozdnem soku najmanjša vsebnost sladkorja in največja vsebnost skupnih titracijskih kislin ter najmanjša masa in število grozdov. Pri obravnavanju brez vršičkanja, je bilo dozorevanje grozdjanajzgodnejše. Pri tem obravnavanju je bila največja vsebnost sladkorja v grozdnem soku, vsebnosti titracijskih kislin, so bile najmanjše,največja pa sta bila število in masa grozdov. Ugotovili smo, da z višino listne stene lahko vplivamo na čas dozorevanja grozdja in čas trgatve. Če pustimo višjo listno steno dosežemo to, da lahko trgamo prej in obratno, z nižjo listno steno lahko trgatev zavlečemo bolj pozno v jesen.

Title:Leaf surface effect on grape and base wine quality parameters used for 'Chardonnay' sparkling wine production
Abstract:The experiment took place in 2018 in Hercegovščak near Gornja Radgona, on the 'Chardonnay' grape variety. The purpose of the task was to check whether the height of the leaf wall and green parts in the vineyard can reduce the negative effects of climate change on the annual development of the vine, thus regulating the time of harvest and also affect the quality of wine suitable for sparkling wine production. The results show that the regulation of leaf area greatly affects the quality parameters of grapes and wine. Via topping, we influence the time of grape ripening and the duration of the developmental stages of the vine. Low topping (above the second wire) had an affectof later and slower ripening of the grapes. On the day of harvest, the grape juice had the lowest sugar content and the highest total titratable acid content and the lowest weight and number of bunches in this treatment. When grown without the topping, grape ripening was the earliest. In this treatment, the number of grapes in the grape juice was the highest, the content of titratable acids was the lowest, and the weight of the clusters was also the highest. The results also showedthat the height of the leaf wall can influence the time of grape ripening and the time of harvest. If the leaf wall if left higher,harvesting can be achieved earlier and vice versa;a lower leaf wall can delay harvesting later into autumn.
