Formation of Gibberellin A3 Glucoside in Plant Tissues

Abstract

Although the physiological action of gibberellin A3 has been extensively studied in recent years, no work has been done about the fate of this compound in the tissue of higher plants. The author observed that exogenous gibberellin A3 is converted in many plants into a glycoside which gives a blue color with Folin-Ciocalteau reagent and induces a growth response in the rice seedling test. This paper describes the experiment with young cucumber leaf disks.
