Soil salinity is an environmental factor limiting crop production, since it affects many plant functions. Being nitrogen metabolism one of the main target of the stress, it has been suggested that the increase of nitrogen nutrition can ameliorate plant response. In this study the effects of salt stress on growth and the activity of enzymes involved in nitrogen assimilation and on the pattern of amino acids and carbohydrates have been evaluated on leaves of sunflower plantlets (Helianthus annuus L. cv. Katharina) cultivated in sand and irrigated daily with Hoagland solution supplemented with 1 or 10 mM nitrate and salt (0 or 100 mM NaCl).
