In order to evaluate the effects of extremely low frequency magnetic field on growth of tomato seedlings (Solanum lycopersicum L.), an environmental controlled experiment was conducted during 2016-2017. After three weeks of germination of seeds and ulterior growth, each tomato seedling was transferred on soil in separate recipient and irrigated with 5ml distilled water daily. After that, the seedlings had been exposed one by one to extremely low frequency (50Hz) magnetic field (ELF-MF) with different values of magnetic flux density (1-2-3 mT) and for different durations of daily exposure. For both type of samples, control and exposed plants, the effects of magnetic field on assimilatory pigments level at different step of growth under daily magnetically exposure were assayed. The results indicated that the exposure to magnetic field increased the chlorophylls level for low magnetic flux density and low exposure duration, respectively. The humidity of the fresh tissue was affected by the magnetic field presence during the fifty days of growth.In order to evaluate the effects of extremely low frequency magnetic field on growth of tomato seedlings (Solanum lycopersicum L.), an environmental controlled experiment was conducted during 2016-2017.
