Abstract

Grožđe je razlog zbog čega se uzgaja vinova loza, a vino je krajnji proizvod u kojem uživamo. U ovom diplomskom radu promatralo se utjecaj na gospodarske karakteristike dviju sorata kod dva različita uzgojna oblika. Cilj istraživanja bio je istražiti utjecaj uzgojnog oblika na gospodarske karakteristike sorata. Pokus je odrađen u pokusnom nasadu sorata 'Rizing Rajnski' i 'Pinot Sivi' gdje su se odabrani trsovi formirali u dva uzgojna oblika, „dvokrak“ i „Guyot“. Pokus je odrađen u istim uvjetima kako bi rezultati bili što vjerodstojniji. Nakon berbe provela su se neka istraživanja poput određivanja kiselina, pH, uvometrija, šećeri. Istraživanjem je dokazano da je pH vrijednost veća kod „dvokraka“ unatoč većem sadržaju kiselina što je suprotno od očekivanog. Broj grozdova, prinos je veći kod dvokraka te se značajno razlikuje od „Guyota“. Masa grozda između „Guyota“ i „dvokraka“ kod sorte `Rizling rajnski` ima značajne razlike dok kod sorte `Pinot sivi` nema značajnih razlika u masi grozda kao ni veličinu.

Abstract (english)

Grapes are the reason vines are grown, and wine is the end product we enjoy. In this diploma thesis, the influence on the economic characteristics of two cultivars in two different cultivation forms was observed. The goal of the research was to investigate the influence of the cultivation form on the economic characteristics of the variety. The experiment was carried out in an experimental plantation of the cultivars 'Rizing Rajnski' and 'Pinot Sivi', where the selected vines were formed into two growing forms, "dvokrak" and "Guyot". The experiment was carried out under the same conditions in order to make the results as reliable as possible. After the harvest, some research was carried out. Research has proven that the pH value is higher in "dvokrak" despite the higher content of acids, which is the opposite of what was expected. The number of grapes, the yield is higher in “dvokrak” and significantly different from "Guyota". There are significant differences in grape weight between "Guyota" and "dvokrak" variety ‘Rizling Rajnski’, while there are no significant differences in grape weight or size in ``Pinot sivi'' variety.
