ISAAC-ALEMAN, Elizabeth et al. Effect of electromagnetic field on mineral content and chemical group during in vitro establishment and multiplication phases of coffee seedlings. Rev Cub Quim [online]. 2016, vol.28, n.2, pp. 692-702. ISSN 2224-5421.

Influence of extremely low frequency electromagnetic fields on minerals content and chemical groups during in vitro establishment and multiplication phases of coffee seedlings was investigated. Untreated coffee plants were considered as control whereas treated plants were exposed to a 60 Hz sinusoidal magnetic field of 2 mT of magnetic induction, during 3 minutes. The results revealed that treated plants, regard to their control shown a significant increase on calcium (55 %), aluminium (73 %) and manganese (43,2 %) levels in establishment phase. The appearance of four sensitive picks was obtained in the embryos tried regards to control embryos. The presence of carbon-carbon double bound, nitrit ion and aldehydes was noted. In multiplication phase increase on calcium (17,9 %), iron (29,2 %), magnesium (5,7 %) and zinc (26 %) levels was regards in treated plants respect control. In conclusion, the findings suggest that the application of 60 Hz magnetic field to in vitro coffee plants may improve the coffee seedlings quality by modifying of ions mobility content ensuring a better quality plants.
