Summary
Changes in tissue contents of some free amino acidscharacteristic of the glutamate and aspartate pathways in tomato plants following increase in the concentration of nitrate or ammonium in the nutrient solution have been studied.
An increase in ammonium produced a massive accumulation of glutamine both in the roots and in the shoot. Asparagine lagged behind and accumulated to a much smaller extent than glutamine. Glutamic acid and proline decreased with increased ammonium whilst aspartic acid and threonine concentrations were less affected. re]19750318
