Description
Preliminary studies in sericea lespedeza, a nonbloating forage legume, indicated that its palatability and digestibility were reduced by high levels of phenolics (Clarke el al., 1939). Another study suggested that younger parts of the shoots are more palatable than older leaves and stems (Donnelly el al., 1971). Nevertheless, younger leaves have been reported to contain higher levels of phenolics (Burns, 1966). Polyphenols have been thought to play a role as growth regulators and in protection against insects and diseases. Also they seem to be associated with lignification (Salatino el al., 1988). The present study was performed to determine whether histological differences in the location of phenolic compounds, especially condensed tannins, could be observed in leaves of sericea lespedeza genotypes of high or low phenolic content. Knowledge of their location could provide clues about their physiological function in plants.

Location of Polyphenols in Leaves of Serciea lespedeza
