The article “Effect of toxicants on plants in the roadside zone of the Tyumen-Petropavlovsk highway” presents studies of morphometric, biochemical characteristics of herbaceous and woody plants, as well as dendrochronological multiparametric studies of trees growing in the zone of influence of highway pollutants. Two species of herbaceous and woody plants were selected for the study in multivariate analyses with control samples. The main part of the article analyzes the morphometric and biochemical characteristics of plants in comparison with the control results. The authors characterize the results obtained in the interpretation of the influence of pollutants on the appearance of plants and adaptation of plants to the toxicants of highways. The results show the difference between the influence of pollution on the growth of deciduous and coniferous woody plants.
