Abstract
The effect of gibberellic acid (GA3) on ion ratios in a dwarf maize mutant (Zea mays L. d1) exhibiting normal growth after hormone treatment has been investigated by electron microprobe analysis. Gibberellic-acid treatment increased the ion content in chloroplasts and vacuoles whereas no change of the ion content was found in the cytoplasm. The relation of these observations to the action of the hormone is discussed.
