Effects of exogenous auxins and inhibitors on potassium uptake in tobacco plants under normal and low potassium levels. a Potassium ion flux after 3 d of starvation. b Potassium ion flux after 5 d of starvation. c Potassium ion content in the roots. Bars represent the averages ± SD of three replicates. Different letters above the bars indicate significant differences between treatments at P < 0.05. NK: normal potassium; LK: low potassium; CK: untreated control IAA: indole acetic acid; NPA: naphthylphthalamic acid
