Effect of gibberellic acid on the uptake and loss of inorganic phosphate from sweet potato slices

  • Published:
Biologia Plantarum

Abstract

Uptake and loss of irorganic phosphate was determined in sweet potato slices ‘aged’ in the presence or absence of gibberellic acid. Concentrations of uptake medium were varied from 0.1 to 1.2 mM. Slices, aged in gibberellic acid, took up considerably less phosphate, at all concentrations than control, whereas efflux from GA3 treated discs was greater than control. Whether treated or untreated, kinetics proved to be biphasic hyperbolas. The results suggested an alteration in membrane permeability induced by gibberellic acid.
