Abstract

Uz veliki broj sorata vinove loze (Vitis vinifera L.), danas se sve veća pažnja posvećuje mogućnosti uzgoja sortata međuvrsnih hibrida s otpornošću na gljivične bolesti i abiotske stresove. Sorte međuvrsnih hibrida nastale su križanjem sorata vinove loze (Vitis vinifera L.) i nekih drugih vrsta roda Vitis. Uz međuvrsne hibride često se veže i prisutnost nekih nepoželjnih aroma (najčešće se navode tzv. foxy ili strawberry-like arome) podrijetlom od aromatskih spojeva identificiranih u najstarijim generacijama međuvrsnih hibrida. Zato se pri evaluaciji ovih sorata njihovom aromatskom profilu pridaje velika važnost. Istraživanje je provedeno na 11 sorata. Analizirane sorte pripadaju međuvrsnim križancima nastalim u oplemenjivačkim programima u Mađarskoj, Njemačkoj i Srbiji: „Bačka“, „Bianca“, „Johanniter“, „Kozmopolita“, „Lisa“, „Merzling“, „Orion“, „Phoenix“, „Sirius“, „Solaris“ i „Staufer“. U ovom istraživanju provedena je analiza sastava i koncetracije aromatskih spojeva lociranih u kožici grožđa. Putem vezanog sustava plinska kromatografija-spektrometrija masa (GC-MS) određen je aromatski profil sorata.

Abstract (english)

With great number of grapevine (Vitis vinifera L.) varietes, ever increasing attention today is given to possibility of growing interspecies hybrids varietes with resistance on fungal diseases and abiotic stresses. Interspecies hybrid varietes are created by crossing with varietes of European grapevine (Vitis vinifera L.) and some other species of Vitis genus. Interspecies hybrids are often associated with presence of some unwanted aromas (e.g. foxy and strawberry-like aromas) that have originated from the oldest generations of interspecific hybrid varietes. Thats why when these varietes aromatic profile is evaluated it is of great importance whether are unwanted aromas present. Research was done on 11 varietes. Analysed varietes belong to group of interspecies hybrids that were created in breeding programms in Hungary, Germany and Serbia: „Bačka“, „Bianca“, „Johanniter“, „Kozmopolita“, „Lisa“, „Merzling“, „Orion“, „Phoenix“, „Sirius“, „Solaris“ i „Staufer“. Analysis of content and concentration of aromatic compounds that are located in grape skin was done in this research. Aroma profile of varietes were determined by gas chromatography coupled with mass spectrometry (GC-MS).
