Effect of electromagnetic wave with high frequency GSM on lipid peroxidation and proline content in leaves in Solanum lycopersicum.

Effects of electro magnetic fields (EMFs) on the «lipid peroxidation and proline amino acid content as a measure for stress of Solanum lycopersicum growth in green house were investigated. Compared with the control cells, exposure of the seedling to Electro Magnetic Field with the EMF producer system of 940 MHZ and 2.8 SAR (high frequency of mobile phone in Iran) for 5 days, 5 hours each day, increased the amino acid of proline by EMF, compared with those of the control group. Level of lipid peroxidation was also increased by EMF. It suggests that EMF could deteriorate proline content defense system of plant cells. In this study the effect of electromagnetic wave with high frequency (940 MHZ) on lipid peroxidation and proline content in leaves of Solanum lycopersicum were evaluated. Plants , 13 days old were subjected for 5 days to two electromagnetic wave treatments: 3 hours for 5 day and 5 hours for 5 days. After 21 days malondealdehyde (MDA) content in leaves of treated plants was measured as an indication of lipid peroxidation .We also measured amino acid of proline as biomarker in abiotic stress.Here electromagnetic field with high frequency (940MHZ) is abiotic stress. Our results showed that electromagnetic field causes an increase in MDA content in leaves compared with control,.which may be due to the induction of oxidative stress and lipid peroxidation. Proline content increased significantly in plants treated in electromagnetic field with high frequency (940MHZ). Increase in proline content may be important for reduction of abiotic stress.
