Abstract. The study aimed to summarise and analyse scientific publications devoted to physical methods for stimulating seed germination and to clarify information on how to implement them. For the review, we used sources on the research topic for 2012–2022. Scientific articles published before 2012 were included in the absence of new publications on a specific aspect of the research topic. For preplanting cultivation of seeds, such physical methods of influence as a magnetic field, microwave radiation, ultraviolet radiation, "cold" plasma, ionizing radiation, ultrasound, pulsed electric field are used. They are considered environmentally friendly and harmless to human and animal health. The considered physical methods of presowing treatment improve seed germination up to 30% and growth rate up to 20%. Their use in the future will make it possible to create productive flow lines for the preparation of a large number of seeds. Among the considered methods, the most simple and suitable for practical application in agriculture should be considered ultrasound exposure and ultraviolet radiation. The remaining methods in their current form are quite complex and energy-consuming for direct use in the processing of a large number of seeds. The active spread of the considered methods is hindered by the insufficient level of knowledge about the biochemical and physical processes that occur in seeds as a result of their processing. To solve this problem, an integrated and interdisciplinary approach is needed, which will allow deepening and accelerating fundamental research, as well as developing practical recommendations for agricultural production.
Keywords: seeds; pre-sowing treatment; germination; stimulation of seed germination; physical methods of treatment.
