Object. To set possibility of the use of sowing of oats the shelled and naked for phytoremediation of soils contaminated with zinc, lead and cadmium in condition of right-bank Forest-Steppe. Methods. Field trials, laboratory testing, mathematical-statistical methods. Results. Conducted experiments affirm that the cultivation of different varieties of oats artificially contaminated with heavy metals ecotopes gray forest soils has led to changes in their quantitative, qualitative, toxicological characteristics of harvest, and also determination of the possibility of using grain. Conclusions. It is established that in condition of right-bank Forest-Steppe on territory with content in the grey forest soil of lead up to 1,000 mg, zinc up to 500 and cadmium up to 20 mg per kg sowings of oats shelled (variety Neptune) and oats naked (variety Solomon) show high tolerance to pollution, so it is possible to conduct a phytoremediation with their use, however the change for the worse of toxicological grain characteristics of these crops makes impossible its use in food and feed purposes.

The review presents the analysis of publications dedicated to problems of using of Bryobionta representatives for bryogeochemical indication and biomonitoring of heavy metals and radionuclides in the environment. Taxonomic structure of Bryobionta is briefly observed, three divisions of Bryobionta are elucidated – Anthocerotophyta, Marchantiophyta and Bryophyta. It is concluded that the most suitable moss species for biomonitoring of heavy metals and radionuclides are representatives from division Bryophyta, such as Hylocomium splendens, Pleurozium schreberi, Hypnum cupressiforme, Scleropodium purum. The mosses have been successfully used in biomonitoring of atmospheric fallout of heavy metals in the environment in Europe for 25 years. A special system of monitoring on their basis is applied in 28 countries of the continent. For the most important moss species used as test-objects of biomonitoring, significant width of their geographic distribution is shown as well as distribution on different substrates of growth (epigeious, epiphytic, epilytic). The main biological peculiarities of mosses which allow to use them for purposes of biomonitoring of heavy metals and radionuclides have been analyzed, i.e. absence of roots, that permits them to derive the main part of nutrients (and pollutants) directly from aerial fallouts – dry (dust) and wet (rain, snow), and high cation exchange capacity of their cell membranes. The most important anatomical and morphological features of three moss groups (endohydritic, ectohydritic, mixohydritic) are briefly reported, and a conclusion about the best suitability of ectohydritic moss species for bryogeochemical indication and biomonitoring of pollutants is made. Results of numerous biomonitoring studies conducted with using of widely distributed moss species in Europe in nature and anthropogenic biogeocenoses are demonstrated. Criteria to mosses as test-objects of bryogeochemical indication and biomonitoring are briefly reported. Physiological adaptations of mosses to stress emerging due to intake of significant concentrations of heavy metals to their phytomass are generalized. Requirements to sampling of moss cover for purposes of bryogeochemical indication and biomonitoring of pollutants are reported. Perspective moss species as test-objects of environmental pollution by heavy metals and radionuclides are proposed for different natural zones of Ukraine: for Polissya zone – Hylocomium splendens and Pleurozium schreberi, for Forest-Steppe zone – Hypnum cupressiforme, for Steppe zone – Tortula muralis and Bryum argenteum.

Abstract. Purpose. Heavy metals can have a negative effect on plants, animals and humans if their concentration exceeds certain limits. Therefore, it is important to establish the characteristics of the accumulation of heavy metals and to determine the elemental composition of aboveground (leaves) and underground (bulbs) organs in plant samples of 8 varieties of Narcissus hybridus hort. (Actaea, Arctic Gold, Cassata, Quail, Sir Winston Churchill, White Lady, Calgary, Pink Parasol) and Camassia cusickii S. Wats. in the urbanized environment of the city of Ufa (Republic of Bashkortostan). Methods. The study of the elemental composition of the samples was carried out according to the method of quantitative chemical analysis “Determination of As, Pb, Cd, Sn, Cr, Cu, Fe, Mn and Ni in laboratory samples of food products and food raw materials by the atomic absorption method with electrothermal atomization No. M-02-1009-08”. Scientific novelty. This work is the first to analyze the results of the content of individual elements in aboveground and underground organs in samples of cultivated floral and ornamental plants in the forest-steppe zone of the Bashkir Ural. Results. It was found that the content of nickel, copper, cadmium, lead, magnesium, iron, chromium in all the samples studied does not exceed the standards specified in the State Pharmacopoeia of the Russian Federation (SP RF). The arsenic content exceeds the standards specified in the SP RF by 3.4 times. Revealed a high intensity of biological absorption of copper. The peculiarity of the accumulation of individual elements by different taxa of the studied plants is noted. It has been established that the concentrations of As, Cu, Pl, Mn, Fe in the aboveground organs are higher than in the underground part of plants; the ratio of the content of Ni, Cr, Cd in aboveground and underground organs is the same. As a result of these studies, it was recommended to use the studied cultivars as a phytoremediator of arsenic.

The research results of on the cultivation of blueberry varieties in the Forest-Steppe zone in eastern Ukraine, namely in the Kharkiv region, are presented. The following results are presented: measurement of biometric indicators, determination of productivity and yield and recommendations for industrial cultivation of the best varieties for the eastern part of the Forest-Steppe of Ukraine. It was found that the most productive and productive variety is Reka, from which it is possible to collect on average 4,70 t/ha of berries, which is higher than the control variety Spartan by 37,4 %. In the Duke variety, these figures were 4,14 t/ha, which is 21,1 % higher than the control.
