The possibility of using a morpho-geometric method for determining the indices of the fluctuating asymmetry of Асе r pseudoplatanus L. leaf for bioindication is evaluated. The material was collected on the roadside territories of motorways of the city of Donetsk with different traffic intensity. The values of the fluctuating asymmetry of A. pseudoplatanus leaf blade, grown in conditions of city roadside ecosystems, are increased with the increase in the transport load, obtained through Procrustean analysis of variance. The morphogeometric method for determining the fluctuating asymmetry showed greater sensitivity in comparison with the use of an index calculated by the normalizing formula based on measurements of individual bilateral features. It is expedient to carry out studies in which the task is to accumulate data on the dynamics of fluctuating asymmetry indices obtained by a morphogeometric method, with a view to the subsequent widespread application of this approach for bioindication and biomonitoring of the state of the environment.
