PRESOWING STIMULATION OF ECHINACEA AND VALERIAN SEEDS WITH ULTRA-HIGH FREQUENCY ELECTROMAGNETIC FIELD

The article presents the results obtained by testing the previously proposed physical and mathematical model of the temperature distribution in the layer of poured seeds when irradiated with a high-frequency electromagnetic field. It has been proven that temperature is one of the factors influencing the consequences of pre-sowing seed treatment. We have found out that, along with heating, other physical processes occur in the seed structure at the level of cell membranes and membrane transport of substances. The transformation of protein structures, the polarization of cell membranes, and the intensification of metabolic processes under the influence of irradiation can lead to changes in the electrical properties of seeds and, as a consequence, can impact on the physiological state, germinability and growth energy of plants. The result of the seed exposure to high-frequency electromagnetic field depends on the electrical characteristics of the seeds. We have developed a technology for the pre-sowing treatment of Echinacea and Valerian seeds in order to obtain more ecologically pure raw materials for pharmacological industry. The study has demonstrated positive thermal and oscillation effects produced by the electromagnetic field on the structural elements of seeds. Based on the method of presowing stimulation of the seeds with a high-frequency electromagnetic field, the optimal modes for irradiation of Echinacea and Valerian seeds have been elaborated. It has been established that boosting the overall resistance of biological tissue, an increase in the polarization of cell membranes indicates an enhancement of metabolic processes and, as a result, stimulates the process of seed germination and rapid vegetation in the early stages of plant development. Theoretical calculations and experimental studies have evidenced positive results doe to implementation of the described technology.
