The effects of low-frequency alternating magnetic field (amplitude 1.5 mT, 15 Hz), hyperthermia (42º) and their combinations on thylakoid membranes function (Hill reaction) and growth characteristics of pea plants (shoot and main root length) were investigated. It has been shown that exposure to alternating magnetic field for 0.5 or 2 hours did not cause changes in the above parameters, while hyperthermia inhibited them. Plants pretreatment with magnetic field before hyperthermia prevented both reduction of Hill reaction and inhibition of shoots elongation, but full return to control values wasn’t occurred. This protective effect of magnetic field let us suggest the common or similar mechanisms of two physical factors - hyperthermia and an alternating magnetic field - influence on plant cells. The weakening of after-stressing treatment negative consequences with low- frequency alternating magnetic field can be used as a methodological procedure for magnetobiological effects detection.
