Abstract
Cu deficiency decreased growth, Cu content and leaf cell wall proportion, increased wilting and altered the cell wall composition of wheat cv. Sappo in flowing sol. culture. At 60 days after sowing the lignin hemicellulose and acetyl groups in cell walls were decreased by Cu deficiency in young leaves and the UV absorption spectra of filtrate from NaOH treated walls were altered. Plants grown without Cu had more phenolic acids and ferulic acid and less p-coumaric acid in the cell walls of young leaves than plants with Cu. This balance was restored when transferred to sol. containing Cu.
