Abstract
Highbush blueberry is a group of endemic species from North America. Its introduction to Belarusian Polesia is associated with transfer of cultivars of this group into an environment with a harsher climate. Adaptive capacity of highbush blueberry allowed its cultivars to adapt to the new environment, fully develop their fruits and complete their vegetation cycle. The property of the plants to fully utilize the time of their vegetation period manifested as shortening of the completion of the main phenophases due to the influence of the temperature factor. In an introduced environment the speed of the phenophases significantly depended on the peak day temperatures, which allowed the cultivars to successfully develop their fruits in an environment where they don’t receive sufficient heat during the vegetation period, as well as to complete the vegetation cycle.

Summary
There are no two places on Earth with identical climate, soil and other conditions. Any plant upon introduction finds itself in a new for it environmental conditions. By reacting to these conditions, the plant begins to adapt to them and change itself within its reaction norm. Adaptive capacity of the introduced plants is cumulative manifestation of their adaptive reaction to the limiting factors of the point of introduction. Highbush blueberry is a group of endemic species growing along the Atlantic Coast in. Cultivars produced from North American blueberries were initially adapted to climate factors of that region. When introduced in Belarusian Polesia the cultivar is forced to adapt to the changes in environmental factors [1]
