“…Therefore, much attention has recently been focused on the response of this plant to heavy metal stresses (Jiang, Wang, 2008). Some plants possess super-accumulative properties with regard to heavy metals: they can accumulate up to 5% of heavy metals (nickel, zinc or copper) in their leaves (as dry mass), which is more than tenfold higher than the values for ordinary plants (Gladkov et al, 2011). Soil parameter such as soil reaction, the organic matter content and quality, soil sorption complex, soil granularity, and oxidation-reduction potential influence the availability of heavy metals in plants (Wang et al, 2015).…”

This paper is focused on the impacts of alkaline and metal deposition on soil and vegetation in the immission field of magnesium factory Jelšava-Lubeník (Slovakia). Soil samples and the foliage of vegetation were obtained from the Jelšava-Lubeník area with specific alkaline pollutants. The examined area is one of the most devastated regions of Slovakia. From the point of view of environmental regionalization, it belongs to an environmentally damaged area of Category 3. The total content of heavy metals in the soil and vegetation (Pb, Zn, Cr, Mn, Mg) were determined by atomic absorption spectrometry and X-ray fluorescence spectrometry. Soil reaction was determined in a solution of 0.01 M CaCl2. Vegetation was assessed by the Braun-Blanquet scale. In conclusion, we can say that spray particles of free magnesium oxide (MgO) strongly influence soil reaction, diversity, and vegetation cover. The research showed that the investigated sites were mostly strongly alkaline; the contents of Cr, Mn and Mg were over the toxicity limit, while the measured values of Pb and Zn did not exceed the limits set by the law. The values that measured significantly above the set limit show contamination that can be considered harmful and toxic. In the monitored species, that is, Agrostis stolonifera, Elytrigia repens and Phragmites australis, an over-limit content of Pb and Zn and toxic contents of Mg and Mn were found.

“…One approach to solve this problem is to create plants resistant to adverse environmental factors using environmental biotechnology (for some ornamental cultures, technologies of introduction into cell culture have been developed [20], for further use of cell selection) [21,22,23,24,25,26]. Plants with greater resistance to copper were obtained [23,25,26].…”

Condition and quality of the lawn grass and flowering plants is important indicators of the level oflandscaping and the urban environment. Copper ions significantly reduce the quality of ornamentalplants. The aim of this study was to assess phytotoxicity of copper for Chrysanthemum carinatum,Festuca rubra and Agrostis stolonifera.High contamination of copper significantly limits the spread of Chrysanthemum carinatum andlawn grass. Chrysanthemum carinatum was less resistant than lawn grass to copper. Chrysanthemumcarinatum can grow only with a low level of soil contamination with copper.

Soil salinization is an important ecological problem in urban ecosystems and agro-ecosystems. Salinization has direct adverse effects on plants. Sodium chloride showed greater toxicity than bischofite to Festuca rubra. We used cell selection to increase the salt tolerance of the plants. We used sodium chloride in all stages of cultivation. We have obtained salt-tolerant Festuca rubra plants. Most Festuca rubra regenerants showed increased salt tolerance. Thus, biotechnological methods can be used to obtain lawn grasses that are resistant to salinity.
