In order to evaluate the allelopatic potential of wheat aquatic extracts against winter wild oat (Avena ludoviciana) at germiantion and vegetative growth stage two expriments were coducted in Islamic Azad University, Shoushtar branch at 2012. Germination expriment was laid out according to Completely Randomized Design with four replications and treatments were various concentration of wheat extract (0, 25, 50, 75 and 100%). At winter wild oat vegetative growth satge , treatments were 0, 25, 50 and 75 % of wheat aquatic extractconcentration and expriment was laid out according to Randomized Complete Block Design with four replications. Results indicated wheat aquatic extract application exhibited gradual rise inhibitory effect on seed germination, seedling weight, antioxidant enzymes activity and -amylase enzyme activity but elevated the mean germination time and malondialdehyde concentration in winter wild oat seedlings. Likewise, seedling weight, antioxidant enzyme activities and sucrose synthetesis enzymes activity were declined with wheat extract application but malondialdehyde concentration increased. In conclusion, wheat aquatic extract decreased seed germination, seedling growth, -amylase enzyme and sucrose synthetesis enzymes activity of winter wild oat.
