We studied specific effects of different doses of natural minerals – analcime (An) and trepel (Tr) – on the growth rate, selenium (Se) content and functional activity of the genome of wheat leaves measured by the RNA/DNA ratio. Our results show that under the influence of An and Tr, especially at low doses (25 mg/100 g sand), there is a significant increase in the content of Se, increased growth rate of leaves of wheat seedlings and decreased RNA/DNA ratio. We have found significant correlations between studied parameters. Our fin­dings suggest that the RNA/DNA ratio can be used as a convenient, reliable indicator of the biological activity of minerals An and Tr, and for quantitative express-estimation of their impact on plant organisms.
