The main limiting factor for olive cultivation in regions located on the northern border of the subtropical zone, as well as in temperate climates, is their low frost resistance. So, the aim of the present study was to evaluate the degree of influence of low negative temperatures on the functional state of leaves of different O. europaea genotypes. Materials and methods.
