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.
The article presents the results of a study of the impact of vehicle emissions on populations of Aesculus hippocastanum L. growing along roads with different traffic intensities. It was found that in areas of heavy vehicle traffic there is an increased level of abortive pollen production. Plant populations increasing the formation of damaged gametes with increasing anthropogenic load on phytocoenoses can be used for phytoindication of the environmental pollution degree. In areas with heavy traffic, pollutants have an average toxic effect on the gametogenesis of Aesculus hippocastanum L. The quality and degree of damage to the pollen zone formed by plants can serve as a bio-test of the mutagenic effect of environmental factors that have a modifying effect on male gametophyte of higher plants.
The article presents the results of assessing the impact of airtechnogenic pollution on the male generative organs of Convolvulus arvensis L. The unfavorable effect of toxic emissions from the landfill of municipal solid waste and vehicles on the processes of microsporogenesis of the populations of Convolvulus arvensis L., which was expressed in the production of large abortive pollen, was established. It is recommended to use the male generative system of the populations of Convolvulus arvensis L. for bioindication of the quality of the state of the environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
