Description
Summary:The young oil glands of Citrus sinensis L. consist of a central group of polyhedral cells encircled by layers of radially flattened cells The oil chamber forms schizogenously through a separation of the walls of the central cells, which are pushed outward and flattened with the expansion and filling of the oil chamber. With further expansion of the chamber, the surrounding cells become vacuolate and fragile, and there are indications of wall degradation suggestive of lysigeny of the cells at this stage. The extensive endoplasmic reticulum in the central cells of the young glands is suggested as the primary site of synthesis of the essential oil.
