Silica Deposition in Plants

Abstract

Silicon has long been known to be present in considerable quantities in the ashes of plants. Richardson (1920) reported its abundance in aerial parts horsetail fern Equisetum and many members of the Gramineae constituting about 50 to 70 per cent of their ashes in the form of its oxide. According to him, amongst all elements in plant materials, silicon, perhaps shows the greatest variation from one part to another of the same plant as also from one plant to another of the same variety.
