ROLE OF COENOTIC RELATIONS IN THE FORMATION OF PLANT COMMUNITIES (ON THE EXAMPLE OF THE LOWER LAYERS OF FORESTS OF THE NORTH-EAST OF UKRAINE)

Dr. Ihor Kovalenko

Abstract: The article focuses on the study of associativity and conjugation of 20 plant species of live ground cover of broad-leaved forests in the North-East of Ukraine. Two groups such as cenosis forming species and species-intruders were determined based on the research findings. The first group (cenosis forming species) includes species with high occurrence and abundance. They are characterized by mutual positive associativity that reveals a significant trend towards common growth. The second group consists of species with negative associativity both among themselves and the species of the first group.
