Abstract
|
|
|
|
| Bioactive compounds were isolated from the jungle rice (Echinochloa colona L.) and their phytotoxicity was evaluated against the weed wild oat (Avena fatuaL.). Tricin (flavonoid compound) purified from E. colonawas tested at 5, 25, 50 and 100 µM on wild oat growth. Tricin suppressed the germination and growth of target weed at higher concentrations (25, 50 and 100 µM). The inhibitory effects of tricin were due to the attenuation of amylase activity, which decreased the starch mobilization and also hampered the activities of antioxidant enzymes. The increase in the non-enzymatic antioxidant molecules (polyphenol, ascorbate and glutathione) was not sufficient to prevent the damage from tricin, because the level of H2O2 and lipid peroxidation was high. More studies are required toevaluate the use of tricin as bioherbicide to control the wild oat. |
