Komarova I. Ecological-biological features of Taraxacum officinale Wigg to the action of heavy metals in the conditions of industrial Kryviy Rih

For the first time in the conditions of the city of Kryviy Rih, namely industrial pollution from the enterprises of the mining and metallurgical complex, the peculiarities and specifics of heavy metals translocation in the soil-plant system were evaluated on the example of Taraxacum officinale Wigg. The specifics of the accumulation of heavy metals by plants from the soil and the subsequent translocation to the leaves in the system "soil-root", "root-leaf" system are analyzed. It has been proved that high level of polyelemental contamination of the environment causes activation of lipid peroxide oxidation processes. The peculiarities of development of generative sphere T. officinale in the conditions of different level of pollution are revealed. Possibilities of seed reproduction of T. officinale depending on different level of stress factor are estimated. The results of the detection and study of adaptation possibilities of T. officinale to different levels of pollution by heavy metals in the environment can be used as criteria for bioindicating the state of the environment. It was established that changes in palynological indices are informative criteria for ecological monitoring and the system of bioindication. The features of seed germination can be used to develop recommendations for assessing the level of soil contamination by heavy metals.
