Silicon (Si) is an element that plays an important role in the physiology of plants (Epstein 1999). Soluble Si occurs mainly as monosilicic acid (H4SiO4) and is taken up by plants in this form, which may polymerize and accumulate on epidermal tissues as amorphous silica (SiO2 nH2O), known as phytoliths, (Bakber and Shone 1966; Ma […]
