[Effect of nickel compounds on glutathione-dependent antioxidant system of pea and maize shoots].
Accumulation of Ni ions in vegetative bodies of 6- and 10-days shoots of peas and maize, as well as the influence of Ni compounds on accumulation of the glutathione reduced form and activity of glutathione-dependent antioxidant enzymes were investigated. It was established, that Ni accumulation by the root system of plants is carried more efficiently, than by leaves. The increase of concentration of these toxic cations in cultivation medium results in the decrease of the glutathione reduced form in vegetative bodies of plants. A general tendency to the increase of antioxidant enzymes activity is shown under the action of Ni compounds.
