Influence of weather and climatic conditions on the viticultural production in Croatia

Abstract

The research includes an analysis of the impact of weather conditions on phenological development of the vine and grape quality, through monitoring of four experimental cultivars (Chardonnay, Graševina, Merlot and Plavac mali) over two production years. In each experimental vineyard, which were evenly distributed throughout the regions of Slavonia and The Croatian Danube, Croatian Uplands, Istria and Kvarner and Dalmatia, the dates of occurrence of the following phenophases are recorded: swelling and opening of buds, the beginning of flowering, the pattern and technological maturity of grapes (harvesting), representing BBCH phases 09, 68, 83 and 89. By analysing multiannual data on harvest deadlines and qualitative parameters of grapes from different regions of Croatia and comparing them with climate data for the same period, we found that the main climatic components affected grape production. In addition, the meteorological data of the Croatian Hydrometeorological Institute also identified trends in Huglin’s index, index sum of the effective temperatures according to Winkler, cold night index and the average air temperature index in the vegetation, for the period 1961-2018. Maps of the four agroclimate indices in 1989-2018 and comparisons with the reference period 1961-1990 indicated climate change over the last 30 years. Due to the increase in the Huglin index of 200 -300°C throughout Croatia, it is possible to change the grapevine varieties in continental Croatia, i.e. planting black wine varieties that need a greater amount of heat, and the possibility of raising winegrowing plantations of early grape varieties in mountain Croatia below 600 m above sea level. The purpose of this research is to increase the adaptability and reduce the vulnerability of Croatian viticulture related to the impact of climate change on grape and wine production through the revision of existing and possible proposal for the establishment of new wine-growing zones in Croatia.

Non-destructive his based analysis for shelf-life evaluation of table grape 

Fast, accurate, and non-destructive analytical techniques based on hyperspectral imaging (hsi) represent effective tools for food quality evaluation. A visible change in the appearance of a fresh product often negatively impacts the perceived quality from a consumer’s point of view.

Soil or geology? And what’s the difference? Some observations from the New World

Observational historical geology seeks to establish the evolutionary history of the surface of Earth. This approach is applicable not only to bedrock, but to the soft material that lies at the surface, the stuff called soil by most people. The geologic perspective provides a view of this material that is quite different from that of soil science, at least as practiced by many in America.

High-throughput screening of physical-mechanical berry skin traits facilitates targeted selection of breeding material with resistance to Botrytis bunch rot and grape sunburn

The ongoing climate change implies an increasing mean air temperature, which is signified by weather extremes or sudden changes between drought and local heavy rainfalls. These changing conditions are especially challenging for the established grapevine varieties growing under cool climate conditions due to an increased risk for fungal diseases like downy mildew (DM) and Botrytis bunch rot (BBR) as well as for grape sunburn. To meet that demand, the scope of most grapevine breeding programs is the selection of mildew fungus-resistant and climatic adapted grapevines with balanced, healthy yield and outstanding wine quality.

Exploring the impact of yeast derivatives on aromatic and sensory profiles of white and red wines: a multifactorial analysis

Specific inactivated yeast derivatives (SYDS) are obtained from s. cerevisiae yeasts by various processes (thermal, mechanical, and enzymatic) and have diverse oenological applications to improve wine quality. However, different impacts on wine sensory and aromas were reported, depending on syds types and fractions, wine matrices, and experimental settings. Few works have examined the impact of SYDS on aromas considering also those on wine macromolecules influencing organoleptic properties.
