Use of impurities to increase yield of seeds for food purposes

The growth-stimulating activity of the drug "Humir", created on the basis of humates, polyethylene oxides, wastes of yeast production, hydrated fullerenes and other BAS is investigated. The introduction of these components in the technology of crop production requires careful study of the properties of drugs based on them in specific soil and climatic conditions of different zones and on different types of seeds. The use of growth regulators is one of the main elements of modern technology. Changing the hormonal status of plants under the influence of exogenous growth regulators increases the activity of metabolic processes in the plant, resistance to biotic and abiotic stresses, increases yields and product quality. Growth regulators are very effective not only for field crops but also for other crops. The use of growth regulators is determined by the stage of ontogenesis, environmental conditions and tasks that are solved by phytoregulators (root formation, removal of seeds from dormancy, regulation of vegetative generative organs, regulation of fruit formation and maturation, regulation of plant stability, product quality, etc.). A number of regulators have a complex effect on the plant, stimulating seed germination, disease resistance, increasing yields and quality. The regulatory effect on the plant organism is closely related to the trophic factor (mineral and carbon nutrition), water regime, metabolism of phenolic compounds, natural conditions. It is possible to regulate the transition of a plant or organ to a state of rest, which is important before laying the fruit and seeds for storage. This served as the basis for our research to create a complex drug with growth-promoting effect. The object of research was selected mustard seeds "Talisman".

Polyethylene oxide matrix tablet swelling evolution: The impact of molecular mass and tablet composition

This article describes the designing of matrix tablets composed of polyethylene oxides (PEOs) with relative molecular masses of 1 × 106, 2 × 106, and 4 × 106. Percolation thresholds were determined for all of the selected PEO formulations (18, 16, and 12 %, m/m), taking into consideration excipients and tablet surface area which significantly increased the percolation threshold. Moreover, the robustness of the gel layer in PEO matrix tablets was evaluated by magnetic resonance imaging under various mechanical stresses (no flow, 12 mL min−1, and 64 mL−1 of medium flow). Correlations between the percolation threshold and gel thickness (R2 = 0.86), gel thickness and the erosion coefficient (R2 = 0.96) was detected. Furthermore, small-angle X-ray scattering of the selected PEOs detected differences in polymer molecular complexity at the nanoscale. Finally, the ratio of the heat of coalescence to the heat of fusion has confirmed the PEO molecular mass-dependent percolation threshold.
