“…Also, among the essential amino acids, the content of threonine increased most significantly. The content of proline, which is related to interchangeable amino acids, and its share in proteins with the use of UFP MoO2 exceeded the control by 0.76 %, which is consistent with the E3S Web of Conferences 282, 05005 (2021) EFSC2021 https://doi.org/10.1051/e3sconf/202128205005 results [9].For example, the treatment of TiO2 1000 mg/kg -1 with UFP the concentration of phenylanin in barley grain increased [5].Treatment of plants with cadmium increased the content of proline in wheat, and a number of other free amino acids: threonine, phenylalanine, terosine, and meotin [6].In oats, when the concentration of copper in the soil was <59.4 mg / kg (1 M HCl), the content of most amino acids increased. Significant differences with the control were found for threonine, glutamic acid, glycine, alanine, isoleucine, leucine, tyrosine, phenylalanine, lysine, and arginine.…”

The use of green mass of annual leguminous crops allows to get a rich amount of protein feed. Therefore, the quality of the green mass must be ensured in the context of sustainable crop production and feed efficiency. Apparently, the use of pre-sowing seed treatment with different-sized metal particles and growth regulators can affect the amino acid composition of crops. In the conducted work, it was found that pre-sowing treatment of seeds with UFP MoO2 increased the content of essential amino acids in peas - 5.75%, millet - 3.61, and in barley with UFP SiO2 - 4.01%. Similarly, UFP MoO2 stimulated the content of proline in the biomass of peas-1.82%, millet-0.15%, barley-0.32% compared to the control.In mixed crops of peas, millet, and barley, the content of leucine-isoleucine increased by -0.36%, lysine-0.13%, tyrosine - 0.04%, proline - 0.76%, threonine-0.36%, alanine - 0.27%, histidine - 0.02%, and glycine - 0.25% compared to the control. The amount of essential amino acids in the mixed crop under the action of the UFP MoO2 increased by 1.38%.

“…Yakhin et al (2009) also observed that the effect of cadmium acetate was manifested in a considerable decrease in the content of phytohormones-cytokinins (isopentenyl adenine (iP), isopentenyl adenosine (iPA), zeatin, zeatin riboside, dehydrozeatin and dehydrozeatin riboside), IAA and ABA both in roots and sprouts of wheat seedlings. On the other hand, many researchers reported an increase in the level of ABA under exposure to heavy metals such as lead (Atici et al 2005;Cenkci et al 2010).…”

“…Over certain limits, heavy metals, that penetrate the cells, induce toxic effects: inhibit the activity of the most enzymes, affect the mineral nutrition and water balance, induce changes in phytohormones activity, affect the membrane structure, a.o. (Seregin et al 2004;Yakhin et al 2009;Corneanu et al 2009), ultimately inducing plant debilitation. The coal, as any ore, containing a discrete amount of primordial radionuclides, naturally occurring, such as K-40, U-238, U-235, Th-232, Ra-226.…”

Introduced in 1750 as an ornamental tree and then in 1852 as a forest tree species, black locust occupied nowadays 250,000 ha in Romania. The tree species is important for its wood (lumber, poles, firewood, etc.), its honey-related production as well as its environmental role (afforestation of sand dunes and sterile dumps).One of the most important activities in the middle basin of Jiu River is coal mining. After 1956 this activity has developed very quickly and two power plants were built in Rovinari and Turceni. As a result, sterile dumps and coal ash dumps have established so it was necessary to restore the area by afforestation. This activity started with the sterile dump Viaduct Rovinari, using Austrian pine and black locust, and continued with others such as Cocoreni and Moi. The most used tree species for ecological restoration was black locust. In order to express the stand structure, diameter at breast height (DBH), total height (H) and crown diameter were measured. The soil analysis were performed and showed differences in the content of heavy metals and radionuclides for both location. The study revealed positive correlations between DBH and H, a stronger one for Moi plantation. Our research highlights the capacity of black locust to establish and grow under very difficult site conditions.
