The effects of shoots and leaf removal on some qualitative parameters of cultivar Chardonnay (Vitis vinifera L.) at Đakovo vineyard district

Pokus za istraživanje utjecaja defolijacije i uklanjanja zaperaka na pokazatelje kvalitete mošta (sadržaj šećera, ukupna kiselost i pH vrijednost mošta) kultivara Chardonnay je postavljen na Fakultetskom pokušalištu u Mandićevcu 2019. godine. Istraživanje je provedeno na ukupno 54 trsa, odnosno uzeti su uzorci sa 18 trsova od svakog tretmana (kontrola, defolijacija i uklanjanje zaperaka). Nakon provedene laboratorijske analize uzoraka, napravljena je jednosmjerna analiza varijance kojom je utvrđeno da provedeni tretmani nisu imali značajnog utjecaja na ukupnu kiselost i pH vrijednost mošta. Značajne i visoko značajne razlike između poduzetih tretmana dobivene su za svojstvo sadržaj šećera u moštu u korist kontroleExperiment for investigation of defoliation and sprout removal on some must quality parameters (sugars, total acidity, pH value) cultivar Chardonnay was set up on Faculty experimental field in Mandićevac during 2019. Investigation was conducted on 54 vines in total, respectively samples were taken from 18 vines per treatment (control, defoliation, sprout removal). After conducted laboratory analysis, one way ANOVA was done which is confirmed that conducted treatment had not significantly influence on must total acidity and pH. Significantly and strong significantly difference between applied treatments was between parameter sugar content in must and control
