Static Magnetic Field Influence on the Activity of some Respiratory Enzymes in Wheat

Abstract

Most of the published studies on magnetic field action on biological systems have examined reactions in animals, while a smaller number of studies have reported magnetic field effects in plants. The effects of static magnetic field on the activity of several key enzymes in plant metabolism, such as malate dehydrogenase, succinate oxidase, succinate dehydrogenase, and cytochrome oxidase in young wheat seedlings, have been investigated in this study. It appears that the observed changes in enzyme activity could be considered to be a result of the influence of the magnetic field on the reactivity of these enzymes, including effects on metal cations that regulate enzyme activity. The results support the idea of the existence of “biological windows,” particularly with respect to exposure time.
