Abstract
Grape Quality Parameters in Western Carpathian Region under Changing Climatic Conditions as Influenced by Drought
Highlights
Grapevine (Vitis vinifera L.) has been grown in Slovakia for thousands of years [Poláček and Poláček, 2009]; it is regarded as a traditional crop in the warmer regions of the country where grapevine is grown on lowlands and mainly on adjacent slopes
Dry periods and drought in Summer was the most often reported among the phenomena related to the climate change perceived by grapevine growers in France, Italy, and Germany, followed by higher temperatures [Bataglini et al, 2009] In all the observed cultivars in our experiment, a negative correlation between the value of Palmer drought severity index (PDSI) and the sugar content was found (Fig.1 a-f) which means that in the years with drought during the berry development and ripening, the sugar content of berries tended to be higher than in the years with humid summer
The drought which occured during the grape berry development and ripening resulted in a higher sugar content in berries
Summary
Grapevine (Vitis vinifera L.) has been grown in Slovakia for thousands of years [Poláček and Poláček, 2009]; it is regarded as a traditional crop in the warmer regions of the country where grapevine is grown on lowlands and mainly on adjacent slopes. Climate factors such as solar radiation and temperature are limiting the extension of the vine growing areas in the region, and weather conditions in individual years influence the quality of grape and wine remarkably.
