Abstract

In this work, we studied the influence of ecological factors (distance from thoroughfares) on photosynthetic characteristics of leaves of four tree species growing in Moscow city. Photosynthetic activity of leaves was assayed by instrumental methods of probing the functional state of the photosynthetic apparatus, using electron paramagnetic resonance for measuring the kinetics of photooxidation of P700 centers, thermoluminescence, and slow induction of chlorophyll fluorescence. It has been shown that the kinetic parameters of the induction curves, as determined from the kinetics of P700 photooxidation and slow fluorescence induction in dark-adapted leaves, are sensitive to variations of plant growth conditions. These parameters can be used as informative characteristics in ecological monitoring.
