The purpose of this study, allelopathic potential assessment of aqueous extract of root, stem, leaf and flower organ of Fumaria parviflora weed on morpho-physiological and biochemical characteractics of Lolium rigidum seedling in hydroponic culture. First, 5% suspension was prepared separately from the organs with help of distilled water and then the resulting suspension solution (extract) was applied on 7 day old of seedlings of Lolium rigidum. Based on the results, various organs of Fumaria parviflora had significant inhibitory effect on growth indices of root length and seedling dry weight, content of chlorophyll b and carotenoids of Lolium rigidum. In most cases, the most inhibitory effect was related to leaf and flower organ extract. But content of prolin, soluble sugar and phenolic compounds were increased compared to control. The greatest increase in these compounds were obtained under leaf and flower organs of Fumaria parviflora. Therefore, by identifying the components of Fumaria parviflora and experiment on other species, maybe be a candidate for production of natural herbicide or proposed a model for the synthesis of herbicides.
