A capacity to determine the provenance of high-value food products is of high scientific and economic interest. With the aim to develop a tool for geographical traceability of Croatian extra virgin olive oils (EVOO), multielement composition and 13C/12C isotope ratio in EVOO as well as the geochemistry of the associated soils were analysed in sampl...

The δ¹⁸O and δ¹³C (analyzed by isotope ratio mass spectrometry, IRMS) and concentration of 22 selected elements (analyzed by inductively coupled plasma—optical emission spectrometry, ICP-OES) in 190 Croatian microvinified and commercial wine samples from continental and coastal winegrowing areas and from three viticultural zones (B, CI, and CII) we...

Monitoring the temperature within the vineyard during the season is important for controling the maturation and planing various production activities in the vineyard. The study displays a description of the spatial variability of the temperature within the vineyard, since it has a strong effect on grape ripening and quality of the grapes. The goal...

The aim of this work was to classifie vine growing regions of Croatia using bioclimatic indices. For the analysis of climatic conditions, linear trends of bioclimatic indices were determined using meteorological observations for all avaliable climatological stations located in vine growing regions of Croatia. Analysis were performed for two differe...

The aim of this work was to investigate existence presence and stability of must specific aroma compounds (monoterpenes C13-norisoprenoids, C6-alcohols, alcohols, esters and carbonyl compounds) and which can be used to establish differences among clone candidates of 'Škrlet bijeli' (Vitis vinifera L.) grapevine variety. The compounds responsible fo...

The concentration of 16 selected elements in 140 wines from two wine producing regions in Croatia was determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Multivariate statistical methods of cluster analysis and principal components analysis were used to evaluate data of these 16 elements in all wines. Differentiation o...

Modern winemaking relies mostly on old traditional cultivars which arose from seedlings developed centuries ago and spread over time and space by continuous asexual propagation retaining original genotype. Due to frequent and large scale cloning their populations accumulated random mutations resulting in genetically slightly heterogeneous individua...

In this study in vitro pollen viability and germination in intact pollens and pol-len tube growth in germinated pollens of five common pomegranate cultivars grown in Croatia and Bosnia and Herzegovina was investigated first time. Pollen viability varied from 36.73% (cv. Konjski Zub) to 51.80% (cv. Barski) in fluorescent diacetat (FDA) test. The ave...

Skrlet bijeli is autochthonous grapevine cultivar grown in continental region. In the year 2000 programme of clonal selection started, 80 elite mother vines were selected and planted into two experimental collections. Most important agronomic traits were measured for 44 evenly distributed clonal candidates were measured and compared to their positi...
