Notes:
Abstract Rye seedlings, tillering plants and crop residues were allowed to decompose in model incubation experiments. Young tissues gave rise to high concentrations of allelochemicals, whereas crop residues did not produce inhibitors. Seven phenolic acids were identified in the investigated materials; p-hydroxybenzoic protocatechuic, gallic, vanillic, syringic, p-coumaric, ferulic as well as benzoic acid. However, neither the level of these acids nor the total content of phenolic compounds corresponded to the level of phytotoxicity determined in bioassays. This demonstrated that, apart from phenolics, other unidentified water-soluble organic compounds were also responsible for the toxicity of rye decomposition products.
