Cell wall template -mediated elaborate mesoscopic silica sttructuresin intercellular spaces of epidermal cells of zoysiagrass leaves were synthesized when SiO(OC~2H~5)~4 was supplied instead of monosilicic acid. The synthesis of organized silica structures in zoysia was correlated with the chemnical form of the silicon applied, reflecting a slower condensation from TEOS and thus providing greater opportunities for structural control by the underlying molecular substrates of cell walls. The composition was estimated by energy dispersive X-ray (EDX) spectra on a scnning electron microscope. All organized structures showed carbon, oxygen and silicon peaks, indicating that their formation differs from natural siliceous process.
