This article presents the measurements of delayed fluorescence from Pinus sylvestris leaves against the functional load on the urban territory. We compare the values obtained with the results of chemical and analytical studies of the soil quality. The sampling was carried out according to a spatial grid designed on the basis of the functional load on the territory. The bioindication method as well as chemical and analytical tests of plant and soil samples taken at each site under study allow to differentiate these locations according to their ecological conditions. We made attempts to assess the degree of influence of various factors on some indicators of plant vitality. Calculations of the correlation coefficient between the content of a number of components in the soil and bioindication data suggest that the photosynthetic activity of plants in urban conditions is more dependent on the state of the atmosphere.
