PALINOMORPHOLOGICAL AND PALINOTOXICAL ASSESSMENT OF AEROTECHNOGENIC POLLUTION IN URBOEKOSISTEMS

The men's generative system of populations of Salix babylonica growing along roads with various level of pollution was investigated. It is established that emissions of motor transport make the adverse effect on generative bodies of Salix babylonica that is shown in the raised production of sterile pollen and its poor quality that is confirmed by exis - tence of reliable differences between the populations growing in zones with various level of aero technogenic pollution. At plants of an inspection zone quite high rate of sterility - 18% of a man's gametophyte was revealed, however production of abortive pollen had been increasing at the populations growing in zones with the average and high level of pollution by 2,7 times. Calculation of an index of sterility lack of distinctions in production of sterile man's gametes between zones with average and high pollution levels have been revealed. The obtained data allowed making the conclusion that the plants that aren't changing production of abortive pollen in process of increase in pollution are tolerant and can be recommended for gardening of urbophytocenosis. Therefore Salix babylonica is offered to use for gardening of anthropogenous phytocenosis as culture, tolerant to a technogenic stress. Indicator of the raised production of abortive pollen grains in system of environmental monitoring behind the objects of environment has been recommended to use testing various degree of anthropogenous loading.
