The quality of red wines depends on the precise harvest date that is linked with the ripeness of a pulp, and skin and seeds. The concentration of phenolic compounds from grape skin and seeds and their extractability during maceration is directly linked to the color and the flavor of the wine. The content of phenolics varies greatly depending on the...

Wild grapevine (Vitis vinifera L., subsp. sylvestris) was found recently along the rivers in the karst landscape of the eastern Adriatic region, which includes Croatia and Bosnia and Herzegovina. The wild grapevine is almost extinct and grows in a restricted habitat in Europe. The anthocyanin profile of red grape berries from naturally growing popu...
Article
The phenolic composition of the Croatian dessert wine Prošek and dry wines Plavac mali and Pošip produced from the same autochthonous cultivars was investigated to determine which phenolic compounds best discriminate between these wine types. The wines were analyzed by the targeted metabolomic method using UPLC/QqQ-MS/MS. Forty-five (45) phenolic c...

Grape cluster architecture is an important trait affecting fruit composition and yield. Damage caused by gray mold (Botrytis cinerea) is directly related to cluster density and some other environmental factors. The aim of this study was to quantify characteristics of fully mature clusters of eleven old Croatian grapevine varieties (Vitis vinifera L...

Project
To date, no information is available on the impact of native non-Saccharomyces yeasts isolated from the Croatian grapes on the aroma profile of wine. The main objectives of the proposed project are: O1: Isolation and identification of the native non-Saccharomyces yeasts from ‘Maraština’; O2. Screening of oenological characteristics of the native non-Saccharomyces yeasts from ‘Maraština’; O3. Determining the influence of specific native non-Saccharomyces yeasts on the varietal and fermentative aroma composition of wine ‘Maraština’.
Project
The main objective of this project is to diagnose and better understand changes that highly pathogenic GLRaV-3 induce in susceptible hosts’ plant in vivo. Distribution screening in autochthonous grapevine cultivars of Southern Croatia will be performed with special attention to GLRaV-3 and its genetic variants. Pure variants present in Adriatic vineyards as well as their combinations molecularly determined by PCR and SSCP methods will be biologically characterised on the set of virus-free indicator plants. Host responses will be observed via changes in nutrient status, hormonal statuses, enzyme activity involved in scavenging stressed condition, photosynthetic and transpiration rates, chlorophyll content, membrane permeability and water content. Special attention will be paid on the interaction between virus and host plants by exploring the dynamic of virus replication throughout the infection processes examined by real-time RT-PCR. Obtained results will enable deeper understanding of the pathogenic potential of GLRaV-3 pure strains and their combinations and the consequences on the autochthonous grapevine cultivars from the Adriatic coast, apart from the well-studied visible symptoms.
Project
The wild grapevine (Vitis vinifera subsp. sylvestris Gmel.) is an ancestor of cultivated grapevine and has never been explored in detail in Croatia. Natural native habitats for this endangered European plant (according to the IUCN Red list of threatened plant species) are relatively untouched forest with significant nearby water. The genetic similarity between wild and cultivated grapes is very high (including sexual compatibility) although the wild grape has not passed through the strict selection process of domestication. Thus, there are possible unique traits and alleles still present in the wild grape genome, which should be explored and used in modern grapevine breeding. The main objectives of this project are to i) assess the overall genetic and phenotypic diversity of wild grape in this region and their relatedness to local cultivated grapevine, ii) preserve the genetic diversity, iii) investigate some morphological and genetic characteristics of wild grape that are of special interest to breeding programs to aid transfer of certain beneficial genes that were not favoured during domestication and human selection bringing unique contribution to this research field. This project will enable the installation of a genetic laboratory for grapevine DNA characterization at the IAC, gather a team of scientists focused on wild grape to deliver multidisciplinary insight, and increase the visibility and collaboration of this Croatian research group with the international scientific community for grape genetic resources, and research collaboration.
