1. Introduction. Silicon (Si) is the second most abundant element present in the earth crust and their uptake could constitute 0.1–10% of the dry weight of terrestrial plants (Epstein, 2009).Silicon is present mainly in the form of mineral silicates, alumino-silicates and silicon dioxide (SiO 2), but most of these forms are inaccessible to the plants.
