Abstract
Prostorna varijabilnost unutar vinograda utječe na mnoge parametre povezane uz kvalitetu grožđa, a posljedica toga je da je teško predvidjeti prinos i kakvoću grožđa i mošta. Ciljanim upravljanjem možemo dobiti uniformne zone unutar vinograda ili kvalitativno različite zone grožđa koje možemo prilagoditi specifičnom tržištu. Precizno vinogradarstvo je važan faktor u povećanju prediktivnosti u uzgoju koji ima za cilj povećati kvalitetu grožđa i profitabilnost. U ovom se istraživanju proučavala varijabilnost vegetativnog i generativnog potencijala sorte 'Pinot crni' u vinogradima Tomac i Šember smještenih u vinogorju Plešivica – Okić, podregije Plešivica, 2020. godine. Na ciljanim trsovima utvrđeni su pokazatelji uroda grožđa - broj grozdova po trsu, prosječna masa grozda (g) te prinos po trsu (kg). Kemijskom analizom mošta prema metodama O.I.V.-a (2001) dobiveni su parametri kakvoće grožđa - koncentracija šećera, sadržaj ukupnih kiselina te pH vrijednost. Bujnost vinove loze opisana je pomoću Ravazovog indeksa te sadržaja dušika (N) u suhoj tvari lista. Rezultati su pokazali da je u vinogradima Tomac i Šember prisutna izražena prostorna varijabilnost u prinosu, bujnosti i kakvoći grožđa. Koncentracija šećera, sadržaj ukupnih kiselina i pH vrijednost pokazali su prostornu varijabilnost te su označene kvalitativno povoljne zone (zone s višom koncentracijom šećera i nižim sadržajem ukupnih kiselina) te kvalitativno nepovoljne zone u kojima su izražene niže koncentracije šećera i više ukupne kiseline. Prema pokazateljima uroda vidljiva je korelacija između manjeg prinosa grožđa i zona visoke kvalitete te između višeg prinosa i zona niske kvalitete grožđa. Prema dobivenim vrijednostima za Ravazov indeks vinograda Šember, manje od polovice promatranih trsova pokazalo je znakove neravnoteže, odnosno pretjerano visoke bujnosti koja za posljedicu ima prosječno manji prinos, ali i višu kvalitetu grožđa.
Abstract (english)
Spatial variability within vineyards affects various grape quality parameters and as a consequence it is difficult to predict yield and quality of grapes and grape juice. With precise vineyard management we can form uniform zones within vineyard or qualitatively different grape zones that we can adjust to specific markets. Precision viticulture is an important factor in increasing predictability in growing, that has a goal to increase the quality of grapes and profitability. In this research we studied the variability of vegetative and generative potential of ‘Pinot noir’ variety in Tomac and Šember vineyards that are located in wine-growing area Plešivica – Okić in subregion Plešivica, in year 2020. Grape yield indicators were established on sampled vines – number of grapes per vine, average grape weight (g) and yield per vine (kg). Chemical analysis of grape juice according to O.I.V. (2001) showed grape quality parameters – sugar content, titratable acidity content and pH values. Vine vigour was described with Ravaz Index and nitrogen (N) content in dry leaf matter. Results have shown that there is a pronounced spatial variability present in Tomac and Šember vineyards in yield, vigour and grape quality. Sugar content, titratable acidity content and pH value have shown spatial variability and higher quality zones have been marked (zones with higher sugar content and lower titratable acidity values) as well as lower quality zones with lower sugar content and higher titratable acidity. Grape yield indicators have shown a correlation between lower grape yield and high quality zones and between higher grape yield and low quality zones. According to Ravaz Index values of Šember vineyard, less than half of tested vines showed signs of imbalance, that is excessively high vigour, that as a consequence gives low yield but also higher grape quality.
