Species specificity of photosynthetic pigment content in the assimilation organs of woody plants (Betula pendula Roth, Tilia cordata Mill., Populus pyramidalis) of urbanized ecosystems of cities in Central Russia (Yelets, Zadonsk, Lebedyan)

The presented work is devoted to the study of species differences in the content of photosynthetic pigments in three common woody plants — hanging birch (Betula pendula Roth), small—leaved linden (Tilia cordata Mill.) and pyramidal poplar (Populus pyramidalis) - growing in urbanized ecosystems of the Central Russian region (Yelets, Zadonsk, Lebedyan). The purpose of the study was to evaluate the adaptive capabilities of the data and establish the relationship between environmental quality and photosynthetic activity indicators. The study revealed the characteristic features of the adaptive behavior of each of the tree species in relation to changes in physiological activity.
