Nationala Aviation University, Kyiv INFLUENCE OF HIGH-FREQUENCY ELECTROMAGNETIC RADIATION ON PROTEIN CONTENT OF Pisum L.sativum CHLOROPLASTS The aim of work was to research influence of high-frequency electromagnetic waves on protein content of Pisum L.sativum chloroplasts and changing in photosynthetic yield. Photosynthesis is one of the major processes on Earth which provides the productivity of plants and supports gas balance in an atmosphere. It is known that different ecological stresses influence the photosynthetic quality, in particularly this is result in the harvesting of agrocenosis and physiological state of plant. Electric, electrochemical, electro-biological processes are necessary part for proper functioning of living organism. Presently the special attention is payed to high frequency electromagnetic fields (HF EMF), in particular, to the range of frequencies from approximately 40 to 100 GHz. Exactly in this range found out a presence of meaningful frequency resonances in the actions on bioobjects. For the research the plants of peas were grown during 14 days under appropriate conditions. First group was control, second group was exposured by high-frequency electromagnetic waves (frequency 57,5-68 GHz, amplitude modulation 6-14 GHz, time 25 minute). During experiment plants were exposured 6 times. For further researches physical and chemical method were applied. The measuring of fluorescence induction of chlorophyll allows to estimate functional activity of photosynthetic apparatus. The indicator is the parameter Fv/Fmax, which is known also as the estimation of quantum yield of photochemistry of FSII. Fluorescence induction was studied in the leaves in vivo under normal physiological conditions according to the time of dark adaptation and changed conditions under the effect of red light (lambda = 450 nm) light which stimulated to excite the photosyste
