The role of exogenous silicon in enhancing plant resistance to various abiotic stressors: salinity, drought, metal toxicities and ultraviolet radiation are presented. The data on possible involvement of silicon in reducing the reactive oxygen species generation, intensity of lipid peroxidation, and in some cases, increasing the activity of enzymes of the reactive oxygen species detoxificators: superoxide dismutase, ascorbate peroxidase, glutathione reductase, guaiacol peroxidase and catalase are analyzed.

Wheat Triticum aestivum L. cv. ‘‘Banti’’ seeds were treated with magnetic fields (+MF) 30 mT, 50 Hz, 30 s to estimate the influence on seed germination, growth rate of seedlings, and plant tolerance under soil flooding (Fl). MF 30 mT, 50 Hz, 30 s did not stimulate growth processes under optimal soil watering, but flooding suppressed the growth of both (-MF; +Fl) and the (+MF;+Fl)-plants. The content of the thiobarbituric acids reactive substances, reflecting the intensity of oxidative processes, was lower in leaves of (+MF) than in (-MF)-plants. Soil flooding intensified oxidative processes in leaves and roots of the (-MF; +Fl) and (+MF; +Fl)-plants; however, this effect was less pronounced in the latter. Ascorbate peroxidase (APX) activity in leaves and roots of (+MF)-plants was higher than in (-MF)-plants during the first days of the experiment. Flooding increased APX activity in all variants; however, in (+MF; +Fl)-plants it was the highest. Guaiacol peroxidase (GPX) activity in leaves of (+MF)-seedlings was significantly higher than in (-MF)-plants at some periods of plant growth. Thus, seed treatment with MF 30 mT, 50 Hz, 30 s did not stimulate seed germination and growth processes in the seedlings, but resulted in an increase of plant antioxidant potential under soil flooding.

Barley (Hordeum vulgare L. cv. “Rudzik”) seeds were soaked in aqueous 10⁻⁶ М 4-hydroxyphenethyl alcohol (4-HPEA) to estimate its influence on seed germination, growth of seedlings, and their adaptive potential under soil flooding conditions. The adaptive potential of the plants was estimated by the concentration of thiobarbituric acid reactive substances (TBARs) and the activity of guaiacol-dependent peroxidase (GPX). It was shown that the 4-HPEA had a stimulatory action on seed germination, shoot and root growth, and biomass production, expressed to a greater extent in the early stage of plant development. Pre-sowing soaking of barley seeds in aqueous 4-HPEA solution increased plant tolerance to the effect of soil flooding, too.
