Diagnostics of Seeding Qualities of Agricultural Crops Seeds Based on Their Electrical Indicators

The article presents a brief overview of relevant works on the measurement and study of bioelectric signals of plant organisms. The methodology and research methods proposed by authors from different countries are explored. Based on the literature studied, a technique for measuring electrical signals of plant organisms is proposed by piercing the shells of various seeds of agricultural crops. Our experiment measures the potential difference between the surface of the seed and the base of the seedling. The results obtained do not allow us to analyze changes in the biopotential of individual cells, but show the general physiological state of the object under study. The development and creation of measuring equipment for studying the biopotentials of plant tissue enable to diagnose seed germination using the express method, both before sowing and when determining the rational regime for treating seeds with physical and chemical factors. Additionally, this technique provides monitoring of the plant organism at various stages of ontogenesis. The results may be the basis for a model of optimal growth and development of plants in various conditions. Further experiments need to be conducted in several types of environments and at different times of the year to identify optimal performance when treated with chemical, biological and physical factors.
