Effects of 940 MHz electromagnetic fields on Malondealdehyde content in Zeamays

Abstract

Electromagnetic fields are examples of abiotic stresses. Nowadays, the world sinks in lesser-known species of messages and signals that encompasses the environment. So living creatures are in exposure of electromagnetic fields. Living cells are charged that are created by ions and free radicals. Electromagnetic fields with interaction between the ions particularly fero magnetic materials such as iron affect on living cells. These environmental factors can significantly affect living cells in a short time and low intensity. In this research, the effects of electromagnetic waves with high frequency of 940 MHZ on biochemical, physiological factors of seedling corn (Zea mays L) have been examined. corn seeding were put for 10 days in medium perlite and Hoagland of ½ strength. After enough growth, group of plants were treated with high-frequency electromagnetic fields with high frequency (940 MHz) for 3, 5, 7 days respectively each day 3, 5 hours. Biochemical and physiological analyzes on the samples after these steps were under control and treatment. The content of photosynthetic pigment chlorophyll a, b in electromagnetic field treatment was not significantly increased. But and level of the anthocyanin pigments in electromagnetic field treatment was reduced significantly.superoxide dismutase in leaves have been observed in high-frequency electromagnetic fields (940 MHz) compared with the control were significantly increased.
