Abstract

We carried out a comparative environmental assessment of the impact of EHF radiation on life expectancy (LE) D. melanogaster, and some morphometric parameters of T. aestivum. The source of the radiation short — wave apparatus “AMFITA-0.2/10-01”. It is shown that the effects of EHF radiation in a dose of 0,30-10-3 J/cm2 in conditions of constant darkness had a negative impact to LE of D. melanogaster of both sexes. EHF irradiation at a dose of 1,82 • 10-3 J/cm2 in dark conditions contributed to the decline LE of males and increased it in females. The effects of EHF radiation in the same dose, but with constant illumination led to a decrease in LE individuals of both sexes. The influence of electro-magnetic radiation (EMR) of EHF at wheat seeds had an ambiguous impact on the length and width of the leaf during the phase of tillering and the phase of elongation. This may indicate participation in responses such mechanisms, which, depending on the exposure dose stimulate or inhibit their development. The findings suggest that the effects of EHF as the primary environmental factor, depends on the genotype of the individuals, their stage of development and irradiation dose. For animal facility conditions of darkness are more favorable than constant lighting. The plant object the most pronounced effects of EHF exposure was observed in the formation of the lamina, which may indicate a characteristic genetic and physiological mechanisms at different stages of individual development. Darkness is more favorable to the animal object than continuous lighting. It was discovered the most significant effect of EHF-radiation on the leaf during the tillering phase. This may indicate the existence of characteristic genetic- physiological mechanisms at different stages of individual development.
