摘要
The article presents the results of a study of the influence of infrasonic treatment on biological and morphofunctional parameters of Hordéum vulgáre seeds. It was discovered that with an increase in the intensity of acoustic vibrations of the acting signal on the seeds, the amplitude of the excitation centers at the initial stage changes according to a linear law (15-30 min), then it stabilizes (45 min), and further exposure to acoustic radiation leads to the "blurring" of the excitation centers and the occurrence of more complex types of oscillations, which in turn leads to a decrease in the amplitude of oscillations. It was found that after exposure for more than 45 minutes, the metabolic process in the cell is non-linear, which can lead to a violation of biochemical processes in the cell up to the destruction of the nucleus and death of the cell. Differences in the degree of transformation of seeds with different duration of treatment are most likely associated with different thresholds and resonance properties of cells. The results obtained allowed us to conclude that infrasound-treated barley seeds show more intensive growth and development at the first stages of germination, which is especially important in dry regions.
