Abstract

Under stress conditions of humidification (35% total moisture in soil), moderate doses of Mn in soil (50 mg / kg) lead to stimulation of primary nitrate reduction process, slight decrease in peroxidase activity and proline content in leaves, as well as increase in vegetative mass of plants. It all indicates to a fuller adaptive potential of plants under such conditions. Excess of Mn in soil (doses 600 – 1200 mg/kg) reduces activity of nitrate reductase, increases activity of peroxidase and rises content of proline in leaves.
