Abstract:
In this paper we studied the mutagenic activity used in agriculture in the conditions
of high temperature. Determined the frequency of metaphases with rearrangements and
frequency of mutation per 100 metaphases. In the experiments, the high temperature
modifying influence on the appearance of chromosome mutations, increasing the
mutagenic effects of the actellic. The effects of high temperature not only on the
frequency of mutations of chromosomes, but also on the spectrum of mutations of
chromosomes in actellic movements.
