Ageratum and salvia were grown in hydroponic solutions containing either NH 4  + , NO 3  - , or both NH 4  +  and NO 3  -  with or without Cl -  to study changes in solution pH and ion uptake rate. pH of both NH 4  +  and NH 4  +  + NO 3  -  solutions was steadily decreased as time passed. A drop in pH front 6.50 to 3.57 within 3 days was recorded with NH 4  + . The pH changes were also affected by the presence of Cl - . The NO 3  -  treatment maintained its initial solution pH over time regardless of the presence of Cl - . pH change by ageratum was greater than that by salvia, especially when plants were in NH 4  +  + NO 3  -  solution. N uptake was maximum in NH 4  +  + NO 3  -  solution with Cl - . Uptake of NO 3  -  was suppressed by NH 4  + , but NH 4  +  uptake was not affected by NO 3  - . NH 4  +  and NO 3  -  counteracted each other in influencing the Cl -  uptake. Uptake of other ion was also affected by plant species as well as N source and Cl - . In ageratum transpiration rate was lowered by Cl -  in both NH 4  +  and NO 3  -  treatments.
