| Abstract: | Multiphasic kinetics were indicated for uptake of ammonium and potassium by intact cirtrus seedlings as measured by a continuous flow technique. Uptake at low concentration, below 10?3M, was biphasis. The patterns for ammonium uptake by 60-day-old and 180-day-old seedlings were similar, but the rates of uptake per g dry weight of root were greater for the younger plants. |
