Abstract

The content of sulfur, nitrogen, phosphorus, ash content in the leaves of annual and perennial species and varieties grown in urban conditions near highways and industrial enterprises of the cities of the Novosibirsk region: Iskitim, Berdsk, Koltsovo, Evsino, Sovetsky district of Novosibirsk was studied. Indications of these substances were determined in the leaves of Hemerocallis hybrida, Iris hybrida, Hosta lancifolia, H. decorata, Salvia splendens, Tagetis patula, Senecio cineraria Malva hybrida, Gatsania hybrida, Alyssum hybrida. The individual features of the accumulation of nutrients and ash in aboveground vegetative organs have been revealed. It was noted that the level of nitrogen concentration and ash content in the leaves of floral and ornamental plants exceeded the values of phosphorus and sulfur by 6–11 times. An increase in the concentration of chemicals and ash in plant leaves in an urban environment has been established.
