Abstract

Silicon-organic compounds in the cell walls of rice seedlings grown in solutions with different levels of CaCl2 and with or without siliconwere investigated by IR and UV absorption spectroscopy. Levels of thelignin-carbohydrate complexes (LCC) in cell walls decreased by silicon deficiency. A bathochromic effect, namely, shifting of the absorption maximum to a longer wavelength, a hyperchromic effect, evident as anincrease in the maximum absorbance in the absorption spectrum, and anabsorbance band at 940 cm(-1) in the IR spectrum, suggesting the combination between an aromatic ring and Si-O, were observed in the LCC from the cell walls supplied with silicon, while only a hyperchromic effect was observed when calcium was supplied. Thus, in the cell walls ofrice plants, evidence was provided for the possible presence of silicon combined with some organic compounds.
