INFLUENCE OF MICROWAVE ELECTROMAGNETIC FIELD ON THE FATTY ACID COMPOSITION OF SEED-LINGS HORDEUM SATIVUM
Abstract
We investigated the variability of fatty acids in tissues of barley seedlings under the influence of electromagnetic fields of ultrahigh frequency (UHF). The object of research was the seeds of spring varieties of barley seed (Hordeum sativum L.). The scheme of experiment included two variants: control – without treatment and electromagnetic irradiation of ultrahigh frequency power of 0,42 kW, 2,45-GHz exposure time 11 sec. In the composition of unsaturated fatty acids in the sprout and roots of seedlings and in the seed coat of barley dominated by polyunsaturated fatty acids – linoleic and linolenic. This causes the high values of the indices of double bonds in the shoots and roots, along with high values of the coefficient of unsaturation in membranes and endosperm. This fact indicates an increase in potential seed viability during processing abiotic stress factor – electromagnetic field of ultrahigh frequency.
Analysis of changes in fatty acids occurring in different organs of seedling showed that in the germ, the endosperm and the shell under the influence of microwave electromagnetic field is reduced content of saturated and, respectively, an increase of unsaturated fatty acids. In roots there was an inverse trend of increasing the amount of saturated and decrease in unsaturated fatty acids. It is established that changes in fatty acid composition of lipids and the activity level of enzymes such as ω9-, ω6 -, and ω3 of desaturase under the influence of electromagnetic fields of ultrahigh frequency also vary according to the organs of seedling. The obtained results give reason to believe that the electromagnetic field of the microwave affects the biosynthesis of fatty acids, lipids and activation of the synthesis of enzymes involved in this process.
