Abstract: The allelopathic effects of leaves, shoot and bark of Quercus baloot Griff. were evaluated under laboratory conditions on Lactuca sativa, Setaria italica and Pennisetum americanum. Aqueous extract, plant parts and rain leachate obtained from Quercus baloot significantly reduced the germination, plumule and radicle growth of Lactuca sativa, Setaria italica and Pennisetum americanum. Litter extracts were inhibitory to Lactuca sativa and Setaria italica and hot water extracts were inhibitory to Setaria italica and Pennisetum americanum. The soil bed, soil extract, and litter bed were inhibitory to in test conditions. In soil intoxication experiment, the shoot and bark exhibited the highest mortality (16-62%) of Setaria italica. The phytotoxicity of Q. baloot depended upon the plant parts and test species investigated. It is suggested that Q. baloot has strong allelopathic potential and the presence of bare or poor understory might be owing its allelopathic effect.
Key words: Allelopathy, Quercus baloot, Phytochemicals, Germination, Growth.
