| description | Biochemical composition was studied in the leaf litter of alien woody species included in the 100 most aggressive invasive species of Europe: <i>Ailanthus altissima</i>, <i>Quercus rubra</i>, <i>Acer negundo</i>, <i>Robinia pseudoacacia</i>, and <i>Elaeagnus angustifolia</i>. Using GC-MS, we detected 187 metabolites in the leaf litter, which are phenolic acids and their derivatives, carbohydrates and their derivatives, polyphenolic compounds, cyclic esters, glycosides, and amino acids and their derivatives. Species-specific metabolites were identified for each species. The main allelochemicals in the leaf litter extract of <i>Q. rubra</i> are determined mainly by the relative abundance of phenolic and fatty acids and their esters, whereas those in the leaf litter extract of <i>R. pseudoacacia</i> are determined by carbohydrates and their derivatives and ester of fatty acid, and those in the leaf litter extract of <i>A. altissima</i> are determined by glycosides. Profiles of macro- and microelements were characterized. It was found that aqueous extracts of leaf litter from all the invasive woody plants under study have a negative effect on the seed germination and initial growth of <i>Vicia cracca</i> and <i>Avena strigosa</i> used for the reclamation of disturbed urban and industrial lands. At the same time, <i>V. cracca</i> is potentially more sensitive. |
