Зависимость скорости митотического деления клеток и частоты возникновения хромосомных аберраций в меристеме корней лука Аllium cepa от частоты воздействующего СВЧ-излучения

At the current level of technology is quite pressing question of the impact of local sources of microwave radiation and electromagnetic smog on biological objects. According to current literature the effect of fluctuations of different frequencies, modulation and intensity give a very ambiguous effects. A deep study of the mechanisms of interaction of periodic oscillations of the fields and living cells may help to reduce the negative impact factor of EMR on the human body. In this paper, the biological test systems used Allium test involves taking into account the mitotic activity and the frequency of chromosomal aberrations in the root meristem of onion Allium cepa. To assess the effect of radiation on the model object of the experimental setup used, ensure consistent environmental factors in a series of experiments, as well as the screening test object on the external background electromagnetic radiation. The experimental procedure provides exposure of the root meristem, the shielding of the remaining parts of the plant to prevent the combined effect on the growth processes. The studies found inhibitory effect of radiation on the mitotic activity, and a significant mutagenic effect of EMR with frequencies in the range of 800-1860 MHz.
