Study of Effects of Extremely Low Frequency Electromagnetic Radiation on Biochemical Changes In Satureja Bachtiarica L

Absract- Plants are organisms that are exposed to various abiotic and biotic environmental impacts. Plants are able to recognize and respond to their surrounding environment with high specificity. Electromagnetic field radiation is an important effective stress factor on growth and development of plants. Our research were focused on plants grown from wet pretreated seeds with low frequency electromagnetic field exposure and compared with the control. Three replicates were used in the experiment with 30 seeds in each samples. The wet seeds treatment were spread on the moist filter papers in Petri dishes and then were placed in the middle parallel coils of electromagnetic radiation generator and were exposed by a magnitude of 1mT to 2hr. Untreated seeds were used as control under similar condition. It means they were placed in the similar coil but not connected to the power. Study of morphological and growth of seedlings showed that in treatment samples in comparison to control the percentage of seed germination and average of root length increased but different of root length was not significantly. A significant decrease in mean of shoot length rate of Leaf area fresh and dry weight was abserved Also caused significant increase in activity of non-enzymatic antioxidant content in treatment samples in comparison of control.
