Abstract:
Origin and development of secretory cavities in stem,leaf,root of Ginkgo biloba were studied with light microscope. The results indicate that except in root there is no secretory cavity,secretory cavities initiate in the same pattern from the other organs examined. The mode of formation of the cavities is schizo lysigeneous pattern. The initial secretory cells appear as a clump of very dense cells surrounded by more vacuolated cells. All these cells become rapidly vacuolated and move aside schizogeneously leaving a central empty space. The secretory cells are collapsed following the development of secretory cavities.Finally, the cavities are surrounded by a ring of densely stained secretory cells and layers of sheath cells.
