Changes in the polyphenoloxidase activity in the leaves of four cultivars and one subspecies of Olea europaea L. were studied during the cold periods of 2016-2019 years on the Southern Coast of the Crimea. Nikitskaya cultivar was used as a model of high frost resistance, while Correggiolo cultivar and the subspecies O. europaea subsp. cuspidata were models of low frost resistance. It was found out that the polyphenoloxidase activity depends on weather conditions during a particular cold period and it almost independent of the degree of frost resistance of the studied genotypes.

Dynamics of total phenolic compounds content in the leaves of four cultivars and one subspecies of Olea europaea L. were studied during the cold periods of 2016-2019 years on the Southern Coast of the Crimea. The concentration of phenolic substances ranged from 642 to 1332 mg/100 g of fresh biomass. It was found out that the content of phenolic compounds depended on weather conditions during a particular cold period and it did not almost depend of the degree of frost resistance of the studied genotypes.
