Abstract: | Infrared absorption spectra of film specimens of the epidermaland parenchyma cell walls of the third internode of pea stem,before and after protease treatment and after treatment forremoval of lipid materials, pectic substances and hemicellulose,were recorded, and characteristic bands in the spectrum of thewall were assigned. Polarization spectrum measurements of thewall provided evidence indicating that the non-cellulosic polysaccharidematrix as well as cellulose microfibrils has an oriented structurein the wall which changes during extension growth as well asupon mechanical extension of the walls.
