Abstract: This study is an attempt to analyze the allelopathic effect of various organs of walnut on germination of wheat experimentally and in a quiet accidentally frame of 10 treatments and 4 replications for it. The treatments of the experiment included an aqueous extract of the root, leaf, and fruit\\\'s green skin (each of them in concentrations of 25, 50, and 100% percent) and distilled water (control). The Results showed that the strong allelopathic effect of the extract of various organs of walnut on germination of wheat seeds in such a way that the statistical comparison indicates the reduction of germination percentage of seeds in treating the aqueous extracts in comparison with control in the level of one percent. Moreover, the results indicated that the extract of the fruit\\\'s green skin has a stronger allelopathic effect comparable with the leaf and root.
