Abstract

The investigation of the electromagnetic irradiation (EMI) with extremely high frequencies (EHF)- 41.8 GHz, 42.2 GHz, 50.3 GHz and 51.8 GHz and low intensity flux capacity (0.6 mW.cm-2 ) of seeds and growth of germs of wheat (Triticum aestivum L.) has been carried out. The effect of EMI on lipid peroxidation and antioxidant system function of wheat shoot cells has been also studied. It has been shown that at irradiation of germinating seeds the increasing of wheat germ mass as well as lipid peroxidation rate is observed. At the same time EMI-induced oxidative stress was indicated by the markedly change of catalase (CAT) activity depending on EMI frequency used and exposure duration.
