Accumulation and radial transport of ions from potassium salts by cucumber roots

Cooil, B. J.

K+ accumulation is insensitive to the anion supplied with it at a solution concentration below 1 mM. Rates of K+ transport to the xylem from the same solutions are, however, dependent upon the anion present and decrease in the order NO3- >> Cl- > SO4--. Parallel effects on rates of exudation and anion transport result from the kind and the concentration of the anion supplied and the time of exposure to the solution.
