Abstract
Vršikanje je uobičajeni ampelotehnički zahvat kojim odstranjujemo vrhove mladica vinove loze. Učinci ovog zahvata su višestruki. Njime se reducira bujnost i zasjenjenost, odnosno povećava se prozračnost mikroklimata trsa i stvaraju nepovoljni uvjeti za razvoj gljivičnih bolesti. Smanjenjem zasjenjenosti utječe se na poboljšanje kvalitete grožđa. Odstranjivanjem vrhova mladica eliminiraju se mjesta najvećeg izljeva asimilata i potiče bazipetalni transfer asimilata što utječe na bolji razvoj cvjetova i intenzivniji proces dozrijevanja grožđa, ovisno o tome kada se vršikanje izvodi. S obzirom na navedeno, provedeno je dvogodišnje istraživanje (2017./2018.) na sorti ’Traminac crveni’ (Vitis vinifera L.) uzgajanoj u zagrebačkom vinogorju, u kontinentalnim klimatskim uvjetima, kako bi se proučili učinci različitih termina provedbe zahvata vršikanja s obzirom na prinos, primarni sastav te hlapljive spojeve grožđa. Pokus je postavljen po slučajnom bloknom rasporedu, te se sastoji od tri termina vršikanja: poslije cvatnje, u lag fazi i u šari. Varijanta bez vršikanja također je uključena u pokus. Pokusom se ustanovilo da vršikanje ne utječe na prinos, ali može utjecati na sastav grožđa i hlapljivih spojeva, ovisno o vremenu vršikanja i godini.
Abstract (english)
Hedging or shoot topping is common ampelotehnical procedure which removes the shoot tips. The benefits of this procedure are multiple. Shoot topping reduces vegetation and shadowing effect which results in favorable vine microclimate and reduces the attack from fungal diseases. Reduced shadowing results in grapes of higher quality. Shoot topping also eliminates places of highest asimilate outflow and stimulates basipetal transfer of asimilates which results in better flower development and intensifies the process of grape ripening, dependent on when the shoot topping is performed. Considering all the above, a two year research has been performed in 2017. and 2018. on cultivar 'Gewurtztraminer' (Vitis vinifera, L.). Experiment took place in vineyarding region Zagreb in the conditions of continental climate. The main task of research was to observe how timing of shoot topping affected yield, grape primary composition and grape volatile compounds. Experiment was set on random block design, and it was composed of 3 shoot topping timings- after bloom, in lag phase of berry development and at the beginning of verasion. A treatment without shoot topping was also included in experiment. The results showed that the shoot topping does not affect the yield but it can affect grape composition and aroma compounds depending on the time of shoot topping and the year.
