Bean plants were cultured on Hoagland's water solution for one or eight days. The following growth regulators: kinetin (10-7 M), GA3 (10-6 M), IAA (10-6 M) or ABA (5 x 10-5 M) were introduced into solutions for 24h. The regulators were found to have a different effect on the potassium level in leaves and roots depending on whether it was assessed I or 8 days after treatment. The mechanism by which growth regulators affect the processes of ion uptake and transport and their relation to growth are discussed
