PLANTS OF MEDITERRANEAN ORIGIN IN ODESSA’ URBANOFLORA
Journal Title: Вісник Одеського національного університету. Біологія - Year 2016, Vol 21, Issue 1
Abstract
Odessa appeared as port in the steppe zone’ south, where ships called to from different regions, one of them was Mediterranean, where trade ways were from east to west etc. The aim of our investigation was the discovering and analysis of plants in modern flora of Odessa, which appeared from Ancient Mediterranean Subkingdom (by A. L. Takchtadgan). We worked in 1985-2015 on the territory of city’ different regions. It was determined the systematical composition of plants, analyzed their life forms, ecobiomorphs, economic value and chronotypes. In modern city’ flora it was found 282 species of seed plants from Mediterranean from 184 genus and 60 families. In systematical spectrum, the most of species belong to Brassicaceae, Rosaceae, Asteraceae, Poaceae, Lamiaceae, Fabaceae, Apiaceae, Chenopodiaceae, Pinaceae. Eight other families have species exclusively from Mediterranian. The biggest are genus Cotoneaster, which has 7 species, and Sisymbrium, Geranium, Pinus (5 sp.). Nine genus have 4 species. Between life forms the most are annual’ plants and monocarpics. Species of trees and bushes are twice as lesser then species of herbaceous. Between hygromorphs prevail mesophyte fraction and between heliomorphs – heliophyte. There are more kenophytes in time of dropping in. It allow to suppose that activity of trade and other connections enlarged in XVIII-XIX centuries. In economic value, there are more decorative, officinal, oil-bearing, food plants and weeds. We suppose that the majority of investigated plants appeared in Odessa’ flora as economic value.
