Abstract
In plants of wheat (Triticum aestivum L.) grown in the media with nitrate (NO 3 − plants), ammonium (NH 4 + plants), and without nitrogen (N-deficient plants), the response to oxidative stress induced by the addition of 300 mM NaCl to the nutrient solution was investigated. Three-day-long salinization induced chlorophyll degradation and accumulation of malondialdehyde (MDA) in the leaves. These signs of oxidative stress were clearly expressed in NO 3 − and N-deficient plants and weakly manifested in NH 4 + plants. In none of the treatments, salinization induced the accumulation of MDA in the roots. Depending on the conditions of N nutrition, salt stress was accompanied by diverse changes in the activity of antioxidant enzymes in the leaves and roots. Resistance of leaves of NH 4 + plants to oxidative stress correlated with a considerable increase in the activities of ascorbate peroxidase and glutathione reductase. Thus, wheat plants grown on the NH 4 + -containing medium were more resistant to the development of oxidative stress in the leaves than those supplied with nitrate.
