Zusammenfassung:The dynamics of the content of various xanthophyll pigments in leaves of spring wheat during
 vegetation at two contrast levels of nitrogen supply was investigated. At a high level of nitrogen
 nutrition, the contents of violaxanthin, lutein, neoxanthin, anteraxanthin, and zeaxanthin per
 1 dm2
 of the leaf surface increased from tillering to milk grain ripening. At a low level of nitrogen
 nutrition, the increase was less intensive, and the period of its rising was shorter (limitation by
 the phase of earling). The contents of violaxanthin, lutein, and neoxanthin per 1 mg chlorophyll
 were risen during vegetation and did not depend on the level of nitrogen supply. But the relative
 content of zeaxanthin was higher at nitrogen deficit nutrition. The results testify to the close
 interrelation between the contents of xanthophylls and chlorophylls and to the increase of the
 defensive role of zeaxanthin under stress conditions induced by nitrogen deficit.
