Climatic features of photosynthesis in the leaves of some evergreen plants of the Absheron peninsula

The work is devoted to the study of the photosynthetic activity of the leaves of some evergreen trees and shrubs introduced on the Absheron Peninsula. Using the LI-6400XT Portable Photosynthesis System RC-P60, 2021 (made in China), the molar amount of CO2 and water, the temperature index inside and in the external environment of the leaf, photosynthetic activity and transpiration rate, relative humidity, and other parameters were determined green leaf. It has been established that there is a direct correlation between the absorbed carbon dioxide and the amount of evaporating water emitted and the presence of the relative humidity of the leaf, which is an indicator of the activity of photosynthesis. The accumulated organic compounds are a source of potential energy during intracellular oxidation. The presence of a dense epidermis of eucalyptus and oleander leaves ensures the economical use of water molecules during transpiration.
