Recherche De Pouvoir Inhibiteur De La Germination Des Extraits De Cleome Arabica L. (capparidaceae)

Résumé: This study is an object of research for potential to inhibit the germination of aqueous extracts of spontaneous plant Cleome arabica L. (Capparidaceae) common species in the northern Sahara, eastern Algeria harvested in the region of Ghardaia. We studied the influence of the aqueous solution of Cleome arabica L.; Seeds of barley (Hordeum vulgare L.) (Poaceae) by experimental as well as the development and growth measures. For this purpose, we used the method of planting in expérimental lots. The application of ten different concentrations of the aqueous extract of plant Cleome arabica L. (100%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20% and 10%) the barley seeds, a can highlight the inhibitory effect of germination of these extracts agains seed of Barley (Hordeum vulgare L.). The results showed that the application of the extract of Cleome arabica L. Seeds of Barley has affected the germination and growth. The study shows that a low concentration 40%, 30%, 20% and 10% results in inhibition rates were 46.67%, 38.33%, 36.67% and 30%, but the concentration of pure and diluted to 90% to 80% and the inhibition rate is high 83.33%, 73.33% and 80%. It is also reported delays in growth seed lots treated with respect to negative controls seeds of lot.
