РЕАКЦИЯ ЯРОВОЙ ПШЕНИЦЫ ИРЕНЬ НА АБИОТИЧЕСКИЕ УСЛОВИЯ ХИМИЧЕСКИМ СОСТАВОМ ЗЕРНА

Abstract

The problem of the chemical composition of fruits and seeds of field crops, depending on abiotic conditions, requires further investigation and is an urgent task. The aim of the research was to study the reaction of spring wheat Iren to abiotic conditions by the chemical composition of the grain. The research tasks are to determine the chemical composition of grain by 70 elements; to reveal differences in the content of chemical elements in grains, grown in various abiotic conditions. The object of research is the grains of spring wheat of Iren variety. Samples of Iren spring wheat grains of 2014 and 2015 years harvest were taken to determine the content of 70 chemical elements Agricultural consumers’ co-operative named after Michurin of Vavozhskiy district of the Udmurt Republic. The content of 70 chemical elements in grain was determined in the Analytical Certified Testing Center (ACTC) of All-Russian Scientific Research Institute of Mineral Raw Materials named after N.M. Fedorovskiy (VIMS). The analysis method is mass-spectral with inductively coupled plasma (MS) + atomic emission with inductively coupled plasma (AE) according to the NSAM technique №512-MS. The reaction of Irene spring wheat to abiotic conditions was expressed by a different content of 45 chemical elements in the grains. The concentration of 25 chemical elements in the grain over the years of research did not differ. Grain, grown in the abiotic conditions of 2014, contained more lithium, boron, sodium, aluminum, calcium, vanadium, chromium, cobalt, nickel, copper, zinc, gallium, germanium, arsenic, selenium, rubidium, yttrium, zirconium, niobium, palladium, tin, lanthanum, cerium, neodymium, hafnium, tantalum, tungsten, iridium, mercury, lead, thorium. In the abiotic conditions of 2015, the grains had a higher content of magnesium - by 255.3, silicon by 6.1, phosphorus by 738.8, sulfur by 153.2, potassium by 871.9, titanium by 6 , 23, manganese - by 19.4, iron - by 9.6 μg / g, relative to similar indicators in the grain crop of 2014.
