Abstract
Si deposits in the caryopsis and inflorescence bracts of S. italica were investigated using light microscopy, scanning electron microscopy and electron probe microanalysis. The samples were obtained from Lin Xian, Henan province, N. China and CSIRO, Australia. High conc. of Si were observed in the papillae on the external surfaces of the inflorescence bracts, and in the epidermal cells. In the caryopsis Si was deposited in the aleurone layer. Silicification was heavier in the Lin Xian samples. The heavy accumulation of silica in this crop and the possibility that fragments of plant silica may be implicated in the aetiology of oesophageal cancer in the Lin Xian region are discussed.
