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.

EXTRACTIBLE COMPOUNDS FROM MICROAGGLOMERATED CORK STOPPERS

After bottling, the wine continues to evolve during storage. The choice of the stopper is an important factor in this evolution. In addition to the oxygen permeability of the closure, the migration of stopper compounds into the wine can also have an impact on the wine organoleptic properties. Many studies have shown that transfers of volatile compounds from the stoppers into the wine can happen depending on the type of closure used (1). Moreover, when cork-made stoppers are used, the migration of phenolic compounds from the stopper into the wine can also occur (2, 3).

Flooding responses on grapevine: a physiological, transcriptional and metabolic perspective

Studies on model plants have shown that temporary soil flooding exposes roots to a significant hypoxic stress resulting in metabolic re-programming, accumulation of toxic metabolites and hormonal imbalance. To date, physiological and transcriptional responses to flooding in grapevine are poorly characterized. To fill this gap, we aimed to gain insights into the transcriptional and metabolic changes induced by flooding on grapevine roots (K5BB rootstocks), on which cv Sauvignon blanc (Vitis vinifera L.) plants were grafted.
