According to anatomical studies, the thickness of the cuticle of leaves in T. cordata is 8. 75-12.5 microns, in T. platyphyllos -6.25-8.75 microns. In the zone of industrial and transport pollution, there is a decrease in the thickness of the leaf plate by 5-13%, as well as a decrease in the size of epidermal cells. The number and size of the stomata, as well as their shape, are different in the investigated linden species. The length of the stomata in T. cordata is 22.5-27.5 microns, the width is 15-20 microns. In the transport pollution zones, the stomatal cells of the epidermis of the leaves of the studied species were smaller in size, the number of open pores was also smaller, but the density of stomata per unit area was higher compared to the stomatal cells of the epidermis from the recreation zone. T. cordata reliably responds to atmospheric pollutants, which allows the use of this species for biomonitoring. T. platyphyllos, on the contrary, showed resistance to factors of aerogenic pollution, has a wide adaptive potential of the leaf apparatus, which allows recommending this species for the creation and reconstruction of urban plantations in conditions of increased gas pollution.
