(Capparidaceae). common species in the northern Sahara, eastern Algeria harvested in the region of Ghardaia. We studied the influence of the extract Capparis spinosa L; Seeds of barley (Hordeum vulgare L.) (Poaceae) by experimental as well as the development and growth measures. To this end, we used the method of planting in experimental batches. The application of ten different concentrations of the extract of Capparis spinosa L. (100%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20% and 10%) on seed Barley, was used to highlight the inhibitory effect of germination of these extracts agains Barley seeds. The results showed that the application of Capparis spinosa extract on seed germination affected Orge and growth. The study shows that a low concentrations50%, 40%, 30%, 20%, 10% the results of inhibition were respectively of46, 67%, 46.67%, 41.67%, 38.33%, but the concentration of 100%, 90%, 80%, 70%, 60% of the rate of inhibition is high 91.67%, 83.33%, 63.33%, 51 67%, 50%, respectively. It is also reported delays in growth seed lots treated with respect to negative controls seeds of lot.frExtract, inhibition, Ghardaia Sahara, Capparis spinosa L.Extrait, inhibition, Capparis spinosa L., Ghardaïa, Sahara.
