FROST RESISTANCE OF THE INTRODUCED SPECIES OF TREES IN THE URBANIZED ENVIRONMENT (LUTSK CITY, UKRAINE)

Abstract

The results of determining the frost resistance of nine introduced species of woody plants in an urbanized environment (on the example of Lutsk city) are presented. The effect of low temperatures on woody plants has been experimentally determined. The degree of damage to the tissues of shoots (bark, cambium, wood, core, buds) by direct freezing using a system of coefficients was studied. The basic patterns of tissue damage are established, taking into account their physiological inequality in vital activity and regenerative capacity of plants. A comparative analysis of the assessment of damage to introduced species depending on the freezing temperature is presented.
