Features of the Biomorphological Structure of Grozny Urban Flora

The life form, or a plant habitus as a set of adaptive features reflecting the impact of environmental factors is one of the important indicators of environmental habitat conditions. The study of urban floras identifies directions, dynamics and nature of the anthropogenic transformation of phytobiota and is of interest due to biodiversity conservation and historical significance for understanding phlorogenesis. The purpose of our study is to identify features of the biomorphological structure of the flora of Grozny, reflecting the adaptive potential of its phytobiota. The object is to identify life forms of the vascular plants of Grozny. The work analyzes field data obtained during expeditionary studies of the local flora. The methodological basis is the classification of climamorph suggested by C. Raunkier and the linear system of life forms developed by V.N. Golubev. The modern flora of Grozny includes 737 species which belong to 392 genera, 92 families and 3 divisions of higher vascular plants. The results of the study on the biomorphological structure show the prevalence of hemicryptophytes (51.28%) and polycarpic herbs (52.1%) in the urban flora. There are a lot of plants forming rhizomes (95 species) which is typical of natural communities of middle latitudes. The flora is of mesophytic nature, retains zoning features. It is foreststeppe hemicryptophyte-terophytic and similar to the regional flora. There are no saprophytes and an insignificant share of hamefits. Synanthropization of the flora is due to the apophytic fraction and its adventitization.
