Resumen
The study of magnetic and electromagnetic fields has been shown to have an influence on seed germination, root development, sprouts, among others. The reduction of germination times and, in turn, the increase of germination rates, allow this method to be promoted as a potential for the development of agricultural seeds in a short period of time. The purpose of the review is to evaluate the incidence of Magnetic (CM) and Electromagnetic Fields (CEM) on the germination and metabolism of different groups of seeds in the percentage of seedling germination and quality. To do this, about 50 authors were reviewed through the use of different databases. The search was compiled in a matrix where the important parts of each publication were synthesized in order to filter the information according to the approach that was required. The research showed that CM, CEM improve the germination processes, especially when the seeds are previously imbibed, this is due to the enzymatic stimulation that takes place inside the seed; In turn, these fields improve the elongation of both roots and shoots. The appropriate response to time/intensity depends on the species, since not all respond in the same way when exposed to the same field. Finally, it is recommended to extend the studies on forest species since it is a little explored field that may have a potential as a pregerminative treatment.
