Abstract
In recent years both in Ukraine and abroad is a priority development of a system of biological indicators for environmental monitoring. Important criteria for the latter can be indicators of accumulation of pollutants species – indicator, adaptation of plants at the physiological level and evaluation of their mutagenic activity. To diagnose the viability of the plants for the actions of certain negative factors, such as pollution, can be used various approaches, however they should be based on the definition autecological characteristics of species, which provide their adaptive plasticity. But it should be noted that one such integral criteria is the establishment of features of formation of the generative sphere of plants and its most important product is the seed that allows you to play the whole body. It is therefore relevant are studies of adaptive capacity synanthropic species to the effects of pollutants that has both theoretical importance for the further development of ecological physiology of plants and practical – for bioindication of the environment. But despite numerous studies, the question remains open of the applicability of Taraxacum officinale Wigg for palinoindykatsiyi of heavy metal pollution. In particular, in the steppe zone on the conditions of Kryviy Rih of adaptive capacity Taraxacum officinale Wigg and identification of tolerance to different levels of heavy metal pollution of the environment, was not carried out. The study of adaptive capacity Taraxacum officinale Wigg and identification of tolerance to different levels of heavy metal pollution of the environment can be used as criteria for bioindication of the environment. The results of studies of ecological and physiological features of functioning and development of the reproductive sphere Taraxacum officinale Wigg as the test system can be a scientific basis for the development of methodical recommendations on assessment of state of environment and environmental monitoring. В последние года как в Украине так и за границей приоритетным есть разработка системы биологических показателей для мониторинга окружающей среды. Важнейшими критериями есть показатели аккумуляции полютантов видами – индикаторами, адаптации растений на физиологическом уровне и оценке их мутагенной активности. Несмотря на многочисленные работы, открытым остается вопрос определения возможности использования Taraxacum officinale Wigg для палиноиндикации загрязнения тяжелыми металлами. Известно, что в условиях степной зоны Криворожжя изучение адаптационных возможностей Taraxacum officinale Wigg и выявление толерантности к разному уровню загряднения тяжелыми металами окружающей среды не проодилось. Результаты исследований эколого-физиологических особенностей функционирования и развития репродуктивной сферы Taraxacum officinale Wigg как тест – системы могут быть научным основанием для разработки методических рекомендаций для оценки состояния среды и организации екологического мониторинга.
