title: Relationship between RNA/DNA ratio, growth rate and accumulation of selenium in the cells of wheat leaves under the influence of minerals analcime and trepel.
abstract: 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.
