| description | Background. Pigment concentration is a species trait, and is an integral indicator of adaptive response to changes in environmental factors and the growing conditions. The intensive development of modern cities imposes certain requirements on the selection of plants for landscaping, one of which is a high level of adaptive responses.
Purpose. The purpose of this study was to determine the content of photosynthetic pigments in the leaves of the genus Acer species in urban conditions of the city of Maуkop, the Adygea Republic.
Materials and methods. We used the spectrophotometric method to determine the content of photosynthetic pigments in the leaves of the genus Acer L. species: A. platanoides, A. pseudoplatanus, A. saccharinum, A. negundo, A. campestre in an urban environment of the city of Maуkop and the zone of conditional control (Botanical garden). We carried out statistical processing of experimental data by using the MS Excel 2010 package.
Results. We have revealed that in the conditions of an urbanized environment the total content of chlorophylls is 1.1-2.2 times higher in comparison with that of the zone of control. Taking into account the level of variability of the total content of green pigments in the city, we arranged the studied species in the following order: A. saccharinum A. campestre ˂ A. pseudoplatanus ˂ A. platanoides ˂ A. negundo. The ratio of the amount of chlorophylls to carotenoids reacted very sensitively to the impact of urban environmental factors. A. campestre and A. saccharinum differed from A. negundo, A. pseudoplatanus, and A. platanoides for this indicator.
Conclusion. The study made allow us to state that in the conditions of an urbanized environment, the studied species of the genus Acer undergo restructuring in the structure of pigment complexes. An increase in the synthesis of chlorophylls and carotenoids raises their adaptive capabilities to the negative impact of urban environmental factors. |
