Evidence from a Dwarf Pea Bioassay for Naturally Occurring Gibberellins in the Growing Plant

Nature volume 181, pages 1548–1549 (1958)Cite this article

Abstract

SUBSTANCES with a biological activity similar to that of gibberellic acid have been shown to be present in extracts of seeds of several species of higher plants1–3. Radley4 has published evidence for the presence of such substances in the growing plant, but the specificity of her bioassay method has been questioned5. No other direct evidence for the existence of gibberellin-like substances in the growing plant (as compared with the seed) has been published, although a considerable and growing body of indirect evidence is in favour of this concept6,7. It is the purpose of this communication to bring forward more definite direct evidence for the presence of gibberellin-like substances in the growing plant.
