“…It was established that changes in the fatty acid composition of lipids and the level of activity of enzymes such as ω9-, ω6-and ω3-desaturases under the influence of an electromagnetic field of ultrahigh frequency also have differences in the organs of the seedling. The microwave electromagnetic field affects the biosynthesis of fatty acids, lipids and activation of the synthesis of enzymes involved in this process(Kondratenko et al, 2017).Long-distance transport of fatty acids is impossible in plants. However, each cell of the plant organism contains fatty acids in the composition of membrane lipids.…”

Features are considered of changing the profile of very long chain fatty acids (VLCFA) in the barley seedling composition in connection with the impact of two abiotic factors: microwave electromagnetic field (EMF) and drought. Studies were carried out on monthly seedlings of barley grown in a soil mixture of peat and sand under laboratory conditions. The experimental chime included six options: 1) control, without microwave processing, normal humidification; 2) EMF with a power of 0.42 kW, a frequency of 2.45 GHz, with an exposure of 11 seconds, normal humidification; 3) EMF with a power of 0.70 kW, a frequency of 2.45 GHz, with an exposure of 11 IV International Scientific and Practical Conference "Modern S&T Equipments and Problems in Agriculture" 117 seconds, normal humidification; 4-6) the same options, but grown in conditions of water scarcity. The content of VLCFA was determined by mass spectrometry. The combined effect of EMF and water deficiency changes the profile of very long-chain fatty acids, which is expressed in a significant increase in Erucic acid in all variants. The action of EMF of 0.42 kW power during the cultivation of seedlings under normal humidification itself in an increase in the content of Erucic acid by 1.6 times, and of 0.70 kW power-by 1 9 times. Increased content of Arachidic and Behenic fatty acids. Changes in the profile of VLCFA in leaves under the influence of water stress and EMF are associated with the activation of the main adaptive systems in the body of seedlings.

The work shows the influence of the electromagnetic field of the microwave range (EMF microwave) on the variability of fatty acids and their derivatives in seedlings of corn of different ages. The object of the study was the corn seeds of the Belarusian selection of the Daria hybrid, which were treated with microwave EMF for 12 minutes with a frequency of 64–66 GHz, exposure power 10 mW. The control was untreated EMF microwave seeds. Fatty acids were determined by gas chromatography with mass spectrometry (GC-MS). Analysis of fatty acids and their derivatives, occurring in seedlings of corn of different ages, showed that in the roots and leaves of corn fatty acid metabolism goes in different ways. On the 4th day of growth, the content of the following oxylipins increases in maize seedlings: hydroxymethyl ester of linoleic acid and octadecanoic acid, 2,3-dihydroxy propyl ether by 57.8% and 26.8%, respectively. By the 12th and 14th day of growth, the content of α-linolenic acid, which is the starting material for the synthesis of oxylipins, substantially increases in the roots of corn. Also, unsaturated fatty acids predominate in the roots, saturated in the leaves. Under the influence of the electromagnetic field of the microwave range in the roots of corn, a decrease in the content of saturated and, accordingly, the degree of unsaturation of fatty acids increases. In leaves, on the contrary, there was an increase in the amount of saturated and a decrease in unsaturated fatty acids after EMF treatment of corn seeds. Polyunsaturated fatty acids, linoleic and linolenic, predominate in the seedlings, roots and leaves of corn. In this regard, it can be assumed that the stimulating effect of pre-sowing treatment of microwave EMF on germination, growth and development of corn occurs through the accumulation of unsaturated fatty acids and oxylipins as a response of the plant to exogenous exposure.
