Abstract:In garlic scape there is a distinct boundary layer of cells between the cortex and stele. Its fine structure and possible ruction seem to agree with the endodermoid first defined by Esau[7], hence the frame. Lightand electron-microscopic examination and cytochemical test have revealed that this particular laryer is probably responsible for the withdrawal of cellular contents of parenchyma to the peripheral vascular bundles, during a long period of storage the excised withering scape would thoroughly exhaust itself to give rise to the new apical cloves. As already shown, the laticiferous tubes scattered throughout the cortex are always turgid, and their sap is rich of nutrients in variable proportion[3]. Possibility of mobilizing these nutrients by the aid of endodermoid to join in phloem transport also has been discussed.
