Antioxidant Responses and Adaptation Mechanisms of Tilia tomentosa Moench, Fraxinus excelsior L. and Pinus nigra J. F. Arnold towards Urban Air Pollution

The aim of this study was to assess the antioxidant response towards urban air pollution three widespread ornamental species—Tilia tomentosa, Fraxinus excelsior and Pinus nigra. Saplings were planted in four plots with different anthropogenic impacts, periodic observations performed on their development. Three types biochemical markers, representing plant responses by mechanisms, analyzed: photosynthetic pigments, free proline guaiacol peroxidase activity. Our confirmed that adaptation environment are complex biological processes including physiological changes. As a whole, these experiments revealed studied trees react specific mechanisms pollution, significantly correlated enhancement traffic (p < 0.05). assessed as being very suitable for landscaping due significant tolerance environmentally stressful conditions. Tilia tomentosa also evaluated species it demonstrated good development environment. nigra proven more sensitive versus other two trees. These findings could be useful scientific basis practice terms sustainable management forestry.
