For Romanian agriculture is essential to promote products based on natural extracts. Seaweeds extracts, humic acids, and other natural compounded often enhancing growth, development, abiotic stress tolerance or ability to tolerate plant disease. Many articles show results of using seaweed extracts as biostimulants to improve tolerance to drought or salinity. Most products are extracted from marine algae belonging to the Ascophyllum nodosum species. In our research, we tested the role of SuperFifty® 0-0-8 in reducing the oxidative stress produced by copper increasing in the culture medium of sunflower seedlings. Two levels of copper have been studied (300 ?mol L-1 Cu+2 and 1300 ?mol L-1 Cu+2), compared with variants that contained a combination of copper and seaweeds extract (1:1000). For each variant, 50 sunflower seeds were placed in 9 cm diameter Petri dishes. As a germination support, filter paper was soaked with solution corresponding to each variant. Experiments were conducted in three repetitions. The germination of sunflower seeds was not significantly influenced by the tested doses of copper and by the administration of seaweeds extract. Concentration of 1300 ?mol L-1 Cu+2 produced a decrease in root size, and the seaweeds extract caused a significant reduction in physiological stress.
