FLORA OF THE RIVERSIDE-WATER SIDE OF THE LOWER SECTION OF THE DNIEST RIVER AND ITS TRIBUTARIES ON THE TERRITORY OF THE REPUBLIC OF MOLDOVA

Abstract

A The studied section of the river. The Dniester and its tributaries are represented by 113 species, 103 genera from 55 families of higher plants (Magnoliophyta). The greatest diversity is found in the Asteraceae (21 species) and Poaceae (8 species) families. About 1/3 of the total number of species are represented by the Eurasian element. The spontaneous element of the studied flora is represented by 54 species, and the ruderal element by 36 species. Invasive elements are represented by the species Ailanthus altissima (Mill.) Swingle, Acer negundo L. Amorpha fruticosa L., Ambrosia artemisiifolia L., Grindelia squarrosa Willd.. It was also carried out for all species: determination of the percentage ratio of life forms, biological indices, ecological groups in relation to humidity, the ratio of plant species by origin, the distribution of indicator species by nitrogen (N) in percentage terms and the ratio of plant species in relation to the category trophicity.
