Abstract
While frost is a natural phenomenon in Hungary from autumn to spring, frost damage, causing crop damage and yield reduction or even harvest shortfall, does not occur every year. The aim of the study was to estimate the occurrence and frequency of frost damage in fall, winter and spring using the CarpatClim data base, in the wine regions of Hungary. The daily distribution of the LT50 function between September 7 and May 15, using the Cold Hardiness model which contains 23 grape varieties, the occurrence probability of fall, winter and spring frost damage was determined. The extent of frost damage, frost duration and strength of frost is significantly affected by tolerance of grape varieties. We analysed the extent of fall, and spring frost damage respectively for frost susceptible, moderately frost-tolerant and frost-tolerant grape varieties. We examined the step overs of frost damage thresholds using CARPATCLIM database during the period between 1961-2010. The results not only provide frost damage quantification, but they may also help to judge the complex value of cultivation areas more accurately and to parameterize the crop safety of wine regions. Keywords: frost damage, LT50 function, wine regions, wine grapes, CarpatClim data
