AB  - The use of bioherbicides offers the possibility to suppress harmful weeds by ecologically acceptable methods and thus increase crop productivity. Progress in understanding the mechanisms of bioherbicides action and weed defense response mechanisms, could help in defining
novel weed control strategies. This work highlights the bioherbicide potential of rhizomes of Sorghum halepense L., characterized by a high content of phenolic acids, especially p-hydroxybenzoic
acid (pHB A) and chlorogenic acid (CHL A). Methanol extract of S. halepense rhizome (SHR), and its
major bioactive principles, displayed phytotoxic effects against Chenopodium murale L., which is a
common weed of fields and roadsides. Besides reduction in C. murale seed germination, rhizome
extract of S. halepense applied in the concentrations of 0.01, 0.1, 1 and 2 mg/ml, induced changes
in the activity of antioxidant enzymes in seedlings. Catalase (CAT) activity was increased, while
peroxidase (POX) and superoxide dismutase (SOD) activities were generally decreased, with a few
exceptions (increased POX and SOD activities at 0.1 mg/ml at 0.01 mg/ml SHR, respectively), suggesting that CAT is the major responsible for the elimination of reactive oxygen species generated
during the exposure of C. murale seedlings to SHR. Application of CHL A induced changes in the
activities of antioxidant enzymes, similar to those observed on SHR treatments. The treatment
with pHB A did not significantly change the activity of POX and SOD, while CAT activity was significantly increased at all applied concentrations. These data highlight the phytotoxic potential as
a highly efficient strategy of S. halepense to invade new habitats.
