Abstract
U proizvodnji stolnog grožđa posebna se pažnja pridaje podizanju kvalitete grožđa, a ona se postiže pravilnim i pravovremenim provođenjem različitih ampelotehničkih zahvata u nasadu odnosno na trsu. Kakvoća stolnih sorata, osim po sadržaju šećera i razini ukupne kiselosti, ovisi i o vanjskom izgledu, prije svega masi grozda i krupnoći bobica. Provedeno je istraživanje o utjecaju prorjeđivanja i cizeliranja grozdova na kakvoću grožđa stolnih sorti Cardinal Crveni i Matilde. Uz vizualnu ocjenu izmjeren je sadržaj šećera i ukupne kiselosti u grožđu te prosječna masa grozda i bobice. Opća je ocjena da je zahvat cizeliranja grozdova(CG) te zahvat prorjeđivanja i cizeliranja(CPG) pozitivno utjecao na sortu Cardinal, putem povećanja prosječne mase bobice i razine šećera u grožđu te smanjenjem razine ukupne kiselosti. Zahvati su također pozitivno utjecali na vizualni dojam. Prorjeđivanje grozdova(PG) nije utjecalo na parametre rodnosti, ali je utjecalo na povećanje sadržaja šećera i smanjenje razine ukupne kiselosti te vizualni dojam. Zahvat cizeliranja grozdova te zahvat prorjeđivanja i cizeliranja pozitivno je utjecao na sortu Matilde, putem povećanja sadržaja šećera u grožđu te smanjenja ukupne kiselosti.
Abstract (english)
In the production of table grapes special attention is given to raising the quality of grapes, and it is achieved by regular and timely implementation of various ampelotechnical procedures in the vineyard. The quality of table cultivars, apart from the sugar content and the level of titratable acidity, also depends on the appearance, above all the weight of grapes and the size of berries. A study was carried out on the effect of cluster and berry thinning on the quality of table grapes Cardinal Red and Matilde. In addition to the visual evaluation, the content of sugar and titratable acidity in grapes and the average weight of cluster and berry were measured. In general, berry thinning(BT) and cluster+berry thinning(CBT) treatments had a positive effect on the Cardinal variety, by increasing the average berry weight and grape sugar levels and decreasing the level of titratable acidity. The treatments also positively affected the visual impression. Cluster thinning(CT) did not affect the yield components, but it contributed to the increase in sugar content and to the reduction of titratable acidity and the visual impression. CT and CT+BT treatments had a positive effect on the Matilde variety, by increasing the content of sugar in grapes and by decreasing titratable acidity.
