Abstract

Posljednjih godina, u cijelom svijetu, veliku pažnju vinogradara zaokuplja pojava naglog propadanja trsa vinove loze. Navedena bolest nazvana je eska ili apoplektično venuće vinove loze. Iako eska nije nikakva nova ili nepoznata bolest, ona je do danas zbog svoje simptomatske kompleksnosti i dalje prilično nejasna, unatoč brojnim istraživanjima u svijetu. Do sada se apoplektičnom venuću nije pridodavala posebna pozornost, jer se najčešće javljala na starim trsovima, dok bi se u mladim... More vinogradima simptomi očitovali mnogo godina kasnije, zbog sporijeg napredovanja fitopatogenih gljiva u trsu. U Hrvatskoj je eska, do danas, uočena u većini vinogradarskih područja pa tako i u Kutjevačkom vinogorju. Cilj istraživanja bio je procijeniti pojavu i intenzitet razvoja apoplektičnog venuća vinove loze na području Kutjevačkog vinogorja. Na svakoj od tri odabrane lokacije (vinograd vinarije Bartolović, vinograd obitelji Pavlović te vinograd Veleučilišta u Požegi) promatrano je tisuću trsova vinove loze različitih sorata. Fitopatološkim pregledom nasada vinove loze, provedenim tokom ljeta 2017. godine, dobiveni su rezultati koji pokazuju da je bolest uznapredovala različitim intenzitetima. Na svim promatranim lokacijama, zapaženi su kronični simptomi bolesti u vidu karakterističnih šara, koje se javljaju na listu vinove loze. Najveći intenzitet zaraze zabilježen je u vinogradu obitelji Pavlović, gdje je na ukupno tisuću promatranih trsova sorte cabernet sauvignon, za koju je opće poznato da je jedna od najosjetljivijih sorata vinove loze na bolest eske, njih 11% pokazalo simptome na istu bolest. Na sorti cabernet sauvignon su osim vidljivih, kroničnih simptoma na listu, uočeni i akutni simptomi potpuno osušenih trsova. Na preostale dvije lokacije nije zabilježena ozbiljnija zaraza, a simptomi bolesti uočeni su isključivo na listovima vinove loze. Sorta graševine, u vinogradu Bartolović, pokazala je intenzitet zaraze od 0,9% a na sorti pinot crni, u vinogradu Veleučilišta, uočen je najmanji intenzitet zaraze eskom od 0,6%. Less

Abstract (english)

In the last years, in the whole world, winegrowers pay special attention to the appearance of a disease on vines. The disease is visiable on grape vines. The aforementioned disease is called Esca or Apoplexy. Although Esca is not a new or unknown disease, it is still fairly vague due to its symptomatic complexity despite being researched in the world. Until now, no attention was given to Esca because it often appeared on old vines, while in the young vineyards the symptoms manifested... More many years later due to the slow progress of phytopathogenic fungus in the vines. Today, In Croatia, Esca has been found in the majority of wine-growing areas and in Kutjevo vineyards, as well. The purpose of the research was to evaluate the progress, development and occurence of Esca disease on vines in the area of Kutjevo vineyards. In each of the three selected locations (vineyard Bartolović, vineyard Pavlović and the vineyard of the Polytechnic in Požega), a thousand vines of different varieties were observed. Phytopathological examination of grapevine plantations, which was carried out at three locations during the summer of 2017, showed that the disease was enhanced with varying intensity, depending on the variety of vines and agrotechnical measures. In all observed locations, chronic symptoms of disease were noticed in the form of characteristic stripes, which appear on the vine leaves. The highest intensity of infection was recorded in the Pavlović vineyard, where at a total of thousands of vines of Cabernet Sauvignon variety were observed, commonly known as one of the most susceptible grape variety to the esca disease. 11% of the vines in that vineyard showed symptoms of the same disease. The variety of Cabernet Sauvignon, apart from the visible, chronic symptoms on the leaf, also showed acute symptoms such as completely dried plants were found. There were no serious infections in the remaining two locations, and the symptoms of the disease were noticed only on the vine leaves . The graševina variety in the Bartolović vineyard showed an intensity of 0.9% and the Pinot Noir variety in the Polytechnic vineyard showed the lowest infection rate of 0.6%. Less
