Abstract
Seasonal inductive changes of chlorophyll fluorescence parameters (Chl FPs) of leaves of 9 species of the genus snowberry (Symphoricarpos Duhamel): S. albus (L.) S.F.Blake, S. ×chenaultii Rehder, S. ×doorenbosii Krűssm., S. hesperius G.N.Jones, S. mollis Nutt., S. occidentalis Hook., S. orbiculatus Moench, S. oreophilus A.Gray, S. rivularis Suksd. are studied. For the assessment of the functional state of green plants a method based on the study of correlation of changes in fluorescence intensity of chlorophyll with photosynthetic reactions in chloroplasts of leaves was used. To measure parameters of fluorescence and its inductive changes in the field conditions we used a portable device – a fluorometer "Floratest" (developed by the Engineering Center of V. M. Glushkov Institute of Cybernetics of National Academy of Sciences of Ukraine. The analysis of the content of metal pollutants in the different parts of common snowberry plants (S. albus) was carried out using an atomic absorption spectroscopy method. There was found the high stability of photosynthetic processes in the leaves of most species, which allows the plants to maintain their ornamental features for the long periods of time. The comparative analysis of the accumulation of metal pollutants and induction of Chl FPs of the most common species S. albus allowed us to determine the level of resistance of species to influence of the negative factors of the urban environment (it is quite high). In this case, the negative influence of the extreme conditions on activity of reaction centers and effectiveness of the dark phase of photosynthesis in chloroplasts in the leaves are established. The results of the research allow us to recommend previously tested in Kyiv city conditions introduced snowberry species for the further usage in the conditions of megacities, and in particular in the places with the high level of contamination.
