The allelopathic activity of five species of weeds(Centurea depressa,Hordeum spontaneum,Hordeum .SP,Lolium rigidum and Senesio vulgaris) against 12 cultivars of wheat was investigated.The aqueous extracts of these species Were diluted to 75 and 50 strength.The effect of these extracts on germination and seedling growth of 12 wheat cultivars were studied.The data showed that the allelopathic activity of aqueos extracts of those weeds had differ significantly against wheat cultivars.The weeds had different effects on the percentage of seed germination coleoptile and root length and dry weight of 12 cultivars of wheat. Keywords: Wheat,Allelopathy,Weed,Coleoptile
