Triticum aestivum L. (Wheat grass), one of the members of Poaceae family, has been considered for very efficient therapeutic drugs. Current study was aimed at evaluation of antibacterial properties of two varieties of T. aestivum L. [cv. Tosunbey (drought tolerant) and cv. Sultan 95 (drought sensitive)] which grown in three different stress condition [(1) drought stress; (2) pre-treatment of seeds with acetyl salicylic acid; (3) drought stress and pre-treatment of seeds with acetyl salicylic acid]. The antibacterial activity of the ethanol extracts were assayed against five pathogens (Pseudomonas aeruginosa ATCC 27853, Proteus vulgaris ATCC 13315, Escherichia coli NRRL B-3704, Staphylococcus aureus ATCC 25923 and Bacillus subtilis ATCC 6633) by agar disc diffusion method and micro broth dilution methods. The results of showed that the ethanol extracts from the different treatments studied showed antibacterial activities, with the diameters of the inhibition zone ranging from 8 to 15 mm and 2.5 to 20 µg/mL, respectively. But, the highest antibacterial activity against B. subtilis ATCC 6633 were demonstrated by the extract of T. aestivum cv. Sultan 95 which grown in drought stress and pre-treatment of seeds with acetyl salicylic acid.
