ABSTRACT
The article presents the study results of the frost resistance of sweet cherry varieties of different ripening periods under artificial freezing. The damage degree of various tissues of one- and two-year-old wood, as well as fruit formations, was analyzed. In the group of early-ripening and late-ripening varieties, a significant resistance of the bark to the effect of low temperature was found, the average damage score was 0,7. Among late-ripening cherry varieties Drogana yellow had low-temperature damage to one-year-old wood, while no negative effect on the wood was observed for the Amazonka variety. The highest overall degree of freezing of one-year wood was observed for the varieties Mliivska yellow and Drogana yellow, the lowest values were obtained for the varieties Meotida, Mirage and Amazonka. Dispersion analysis based on a combination of factors confirmed the highest degree of wood freezing for the Mliivska yellow and Drogana yellow varieties.
