%X Glutamate synthase(GOGAT) and glutamate dehydrogenase(GDH) activity in the roots and leaves of rice seedlings were decreased under NaCl stress.NH 4 level in leaves was increased significantly due to NaCl stress,but the content of NH 4 in roots was not altered obviously,irrespective of NaCl treatment.As compared with root, leaf was more sensitive to NaCl stress.The reduction of the activity of NADH GOGAT and NADH GDH in leaves was more than that in roots.Whether NaCl was added or not to the nutrient solution,NADH GDH activity of roots was much higher than that of leaves.Analysis for GS GDH ratio showed that GS GOGAT cycle was main pathway of ammonium assimilation in the control plant roots,but under NaCl stress,GDH pathway was strengthened obviously.Irrespective of NaCl treatment,GS/GOGAT cycle was main pathway in leaves.
