Changes in the Formononetin Content of Detached Mature Leaves of Trifolium Subterraneum

Abstract

Anthocyanin formation is stimulated in the leaves of some plants when the leaves are detached and floated on water or on sucrose solutions and exposed to light (e.g. Eberhardt 1954; Creasy, Maxie, and Chichester 1965). The synthesis of other flavonoids, e.g. flavans, can be increased under these conditions (Creasy and Swain 1966).
