Short-chain fatty acids as growth inhibitors in decomposing wheat straw

  • C. S. Tang
  • A. C. WaissJr.


The aqueous extract of decomposing wheat straw in water was inhibitory to the seedling growth of wheat (Triticum aestivum L.). The major compounds isolated from the toxic fractions were salts of acetic, propionic, and butyric acids. Amounts of these acids increased gradually up to 12 days and the toxicity of the straw extract increased accordingly. Traces of isobutyric, pentanoic, and isopentanoic acids were also identified by gas chromatography-mass spectrometry.
