Agar-diffusion Technique for estimating Gibberellin Production by Plant Organs

Abstract

So far, all published results relating to the gibberellin content of plants, or plant organs, have been obtained by various gibberellin-extraction techniques. This procedure is useful in the determination of the gibberellin content at any point in time, but it is often desirable to be able to estimate the rate of gibberellin production by various plant organs. In the course of our work on the gibberellin relationships of organs in the sunflower plant (Helianthus annuus), we have adopted a modification of the classical technique of agar-diffusion. The method is simple and flexible and, as will be shown, it is reasonably sensitive and quantitative.
