A Contribution to the Root Study of the Evergreen Sclerophylls Anatomy of the Primary Root of Quercus coccifera L.

Abstract

The structure of the primary root of Quercus coccifera , an evergreen sclerophyllous species common in maquis formations in Greece, has been studied by light and electron microscopy with special reference to the differentiation of endodermis. Histochemical identification of phenolic compounds in root tissues has also been carried out. Polyphenolic compound accumulation and extremely thin radial walls of endodermal cells observed in these roots are proposed to be adaptations contributing to a more effective water uptake and transport by the plant.
