title: [Cell-wall composition during inhibition of hypocotyl elongation in the mustard seedling (sinapis alba L.) by inhibitors or phytochrome].
abstract: During inhibition of hypocotyl elongation in the mustard seedling by actinomycin D, hydroxyproline, and continuous far-red via phytochrome 730 the synthesis of cell-wall carbohydrates is impaired in the same manner. Independent of the treatment 12 hrs after its beginning at a relative inhibition of hypocotyl elongation of 80-90% the relative inhibition of the cell-wall carbohydrate content is uniformly about 30-35%. No significant quantitative nor apparent qualitative differences in the sugar and uronic acid content of the pectic, hemicellulosic, and α-cellulosic cell-wall fraction could be detected.
