dc.description.abstract This study focuses on the search for allelopathic activity of the plant Pergularia tomentosa L. were harvested in the northern Sahara, eastern Algeria, on the germination of seeds of barley (Hordeum vulgare L.), (Poaceae). This study allowed demonstrating the inhibitory effect on the germination of barley seeds treated with the aqueous leaf and root extracts of this plant in the Sahara. The pure and diluted to 50% aqueous extracts showed an exceptional ability to inhibit the germination of barley seeds where a maximum rate of 100% inhibition is achieved for low back concentrations, an inhibitory effect on the germination part there observed. In addition, it is found that the root extract seems more phytotoxic than the leaf extract of P. tomentosa L.; Growth abnormalities are still observed in the batches treated with extracts of this plant, also.
