Abstract
Tomato plants were cultivated (from 2 to 23 days after germination) in media with NO −3 , NH +4 , or a mixture of both forms in different proportions used as the N source given with or without 5 mol dm−3 HCO −3 . The accumulation of soluble sugars (reducing sugars and sucrose) and free amino acids was higher in the roots and leaves of NH +4 -fed plants than in NO −3 -fed plants. Starch accumulation in NH +4 -fed plants was higher in leaves (about 28%) and lower in roots (about 37%) in comparison with that of NO −3 -fed plants. Plants cultivated in media containing a mixture of NO −3 /NH +4 were characterized by a lower content of sugars and amino acids accumulation in comparison with that in plants fed with NO −3 or NH +4 . An elevated HCO −3 concentration in the rhizosphere stimulated the accumulation of soluble sugars and free amino acids in all the experimental variants. There were only small differences in the starch content.
