Abstract: The phytotoxic effects and total phenols content (TPC) of H. mantegazzianum was tested on perennial ryegrass (Ryegrass perenne) and winter rapeseed (Brassica napus) seed germination to find their response ex situ. H. mantegazzianum leachates inhibited the germination. The seeds of oil rapeseed germination was 82% in lowest concentration (0.02% w/v) and 0% in most concentrated leachates (0.2% w/v). Nonetheless, the 0.02% leachates of leaf and seed stimulated the ryegrass germination by 17 and 2% over the control, respectively. The TPC varied depending on the hogweed parts and leachate concentration. At 0.2% leachate concentration, the highest content of phenolic compounds accumulated in leaf (89.16 mg mL-1) and seed (67.54 mg mL-1), possibly due to intensive conversion of synthesized materials in these hogweed parts
