In order to improve the sowing qualities of seeds and increase the yield of agricultural crops, the issue of impact on seed material does not lose its relevance at any time. Today, in order to increase crop yields, various processing methods are used, in particular, methods of electrophysical stimulation, protective compounds, pills, etc. A simple method of seed treatment in order to influence the quality of sowing and the future harvest is a primer, the features of the research and the mechanisms of the method have not yet lost interest in science. In recent years, the Taraxacum Officinale plant has been paying special attention in order to prevent environmental and economic problems of our country. In particular, there are many studies on the use of the Taraxacum officinale plant as an object of bioindication of polluted, including urbanized territories.
