Essay

The dissertation describes results of the research concerning changes in the processes of antioxidant system of pleustophyton plants on the example of Lemna minor variety under conditions of water environment pollution with ions of heavy metals, particularly plumbum, cadmium, chrome (VI). It is argued that adaptation of pleustophyton plants to water contamination with heavy metal happens due to some changes in the processes of antioxidant metabolism. Novelty of the work is in the performed comparative analysis of antioxidant potential of different kinds of the representatives of Lemnoideae – Lemna minor and Spirodela polyrhiza. Analysis of enzyme activity in the plants of little duckweed (Lemna minor L.) has been further developed. It can be used for assessment of the conditions of water bodies as life environment for pleustophytes, and the very plant – as a test-object in the methods of phytoindication. The work proposes to introduce the plant of little duckweed into the system of aqua-cultivation in agro-industrial complex of Ukraine for supply of animal breeding industry with bio-forage and the sphere of water-purification – with a biological filter.
