Root uptake coefficient for Cl ions in corn as affected by transpiration rates and solution concentration

Summary

Root uptake rate and root uptake coefficient for Cl ions were determined in corn at two transpiration rates and three solution concentrations. Transpiration rate had pronounced effect on root uptake rate and root uptake coefficient especially at low solution concentration. Root uptake rate increased as the concentration of Cl ions in the solution increased. The root uptake coefficient decreased as Cl concentration in the solution increased from 20 meq/l to 40 meq/l but it did not change when the concentration was raised to 80 meq/l.
