Ampelograpic and genetic characterisation of grapevine genetic resources from Ozalj-Vivodina region (Croatia)

Abstract

Context and purpose of the study– Ozalj- vivodina region is small vine growing area (only about 100 hectares of vineyards), but with significant number of old, ancient vineyards planted between 50 and 100 years ago. Trend of abandoning or replanting ancient vineyards takes place for the last 30 years. This trend results in grapevine germplasm erosion because traditional varieties are replaced with well known international varieties.Few known traditional varieties are dominantly present in ancient vineyards together with many others of unknown identity. Historical data about prevalence and characteristic of varieties on this area are very poor. For this reason, we started a project with the purpose of identification, characterization and conservation of grapevine germplasm in this area.

Material and methods – Three years study (2016-2018) included ampelographic inventarization of ancient or abandoned vineyards in Ozalj-Vivodina area. A total of 61 samples (vines) were selected for further research and identification. Identification in situ include ampelographic description by standard set of OIV (Organization Internationale de la Vigne et du Vin ) descriptors. Genetic identification was performed using nine microsatellites markers recommended by the European project GRAPEGEN06. Genetic profile of samples was compared by national and several international databases for possible matching between profiles or with other varieties.

Results – Based on microsatellite analysis of the 61 samples, 45 different genotypes were detected which were identified as follows: 18 genotypes did not match with any of the varieties from available databases; 6 genotypes were identified as traditional or native varieties from NW Croatia (Plavec žuti, Kozjak bijeli, Dišeća Ranina, Moslavac (Furmint), Plemenka (Chasselas rouge), Graševina (Welschriesling); 8 genotypes were identified as rare autochthonous Croatian varieties from other wine regions; 7 genotypes represent common varieties from other European countries (Chardonnay, Pinot Blanc, Blaufraenkisch, Sauvignon Blanc, Rkatsiteli, Pamid, Chauch blanc; 5 samples represent a rare variety identified in other European countries (for example Gaensfuesser blau) and one genotype was identified as Belina starohrvatska (syn. Gouais Blanc). It is interesting that Gouais blanc was represented with six samples from five different locations even though it was not considered to be a traditional cultivar in this area. Ampelographic study shown that dominant genotypes have white coloured berry (33), followed by red (7) and rouge (2). Three genotypes had no clusters available during research. Three genotypes have specific muscat flavour and two have a female type of flower. This research shows that Ozalj-Vivodina as a small winegrowing area has rich grapevine germplasm preserved.

Comparing vineyard irrigation management based in two different approaches: vegetation indices and SIMDualKc model

Water scarcity, high air temperatures, high vapor pressure deficit, and increasing frequency and intensity of extreme climatic events, namely heat waves, exert huge pressure on viticulture, as is the case of Mediterranean climates. Therefore, farmers rely more and more on irrigation to overcome these constraints. Deficit irrigation is a proved strategy to optimize irrigation efficiency and wine quality. The present study intends to demonstrate the application of precision techniques, namely remote sensing derived vegetation indices (VI) and an open source software, SIMDualKc, to compute crop evapotranspiration using the dual crop coefficient approach (Kcb + Ke), for deficit irrigation management.

The effect of rootstock on water relations and gas exchange of Vitis vinifera cv. Xinomavro

The effect of two rootstocks of different drought tolerance (1103 Paulsen and 3309 Couderc) on sap flow, water relations and gas exchange of cv. Xinomavro (Vitis vinifera L.) was investigated during the 2005 season in Naoussa, Greece. Soil was maintained at field capacity for both rootstock treatments until mid July when a restricted water regime was applied by irrigation cutoff. Sap flow diurnals for the Xinomavro-1103P combination showed a rapid decrease of flow after midday, under water stress conditions.

French wine sector facing climate change (part. 2) : the implementation of the national strategy

This summary follows this made by Hervé Hannin et al. Entitled “French wine sector facing climate change (part. 1) : a national strategy built on a foresight and participatory approach “. The french wine sector has taken a collective approach to the issue of climate change, and has officially submitted its strategy to the minister of agriculture in 2021. This industry policy is the result of multidisciplinary work carried out through the “laccave” project (metaprogramme accaf, inrae) and its prospective study designed to anticipate climate change in the french wine industry (aigrain p. Et al., 2016). French wine professionals decided to structure a strategy to deal with climate change du in particular to the presentation made at the 2016 OIV congress in Brazil.

Techniques to study graft union formation in grapevine 

Grapevines are grown grafting in most viticultural regions. Grapevine rootstocks are either hybrids or pure species of different American Vitis spp. (particularly V. berlandieri, V. rupestris and V. riparia), which are primarily used to provide root resistance to the insect pest Phylloxera. In addition to Phylloxera resistance, ideally grapevine rootstocks should be resistant to other soil borne pathogens and adapted to abiotic stress conditions. New rootstocks have the potential to adapt agriculture to climate change without changing the characteristics of the harvested product. However, high grafting success rates are an essential prerequisite.

The informative potential of remote and proximal sensing application on vertical- and overhead-trained vineyards in Northeast Italy

The application of remote and proximal sensing in viticulture have been demonstrated as a fast and efficient method to monitor vegetative and physiological parameters of grapevines. The collection of these parameters could be highly valuable to derive information on associated yield and quality traits in the vineyard. However, to leverage the informative potential of the sensing systems, a series of preliminary evaluations should be carried out to standardize working protocols for the specific features of a winegrowing area (e.g., pedoclimate, topography, cultivar, training system). This work aims at evaluating remote and proximal sensing systems for their performance and suitability to provide information on the vegetative, physiological, yield and qualitative aspects of vines and grapes as a function of different training systems in the Valpolicella wine region (Verona, Italy).
