Since algae is one of the natural sources of chemical compounds, including nutrients, fats and vitamins, thatstimulate the germination and growth of plants, so the aim of the research was to study the effect of aqueous extracts of Cladophora and Spirogyra at a concentration of (0, 1, 2) % in the germination and growth of three cultivars of the bread wheat Triticum aestivum (Baraka, Buhooth-22 and Sham-6) through the application of the pots experiment. The results showed that the aqueous extract of the algae affected positive  the assessed variables increase considerably as the concentration increased, and treatments at concentration (1 and 2%) had an encouraging effect on the germination and growth of plants of both cultivars  Buhooth-22 and Baraka, while cultivar Sham-6 was less responsive to the extracts.
