ABSTRACT

Growing environmental concerns have contributed to the search for, and development of, the use of environmentally friendly substances. Such innovative thinking will lead to the replacement of chemicals by biological surfactants, culminating in an increased use of biosurfactants in several key areas, including agriculture. Hence the crucial importance of evaluating the effect of biosurfactants on seed germination and development. In vitro tests of seed germination were conducted on different species of cultivars: lettuce, corn, soybean and sunflower. Evaluated biosurfactant concentrations ranged from 0.25 to 1.00 g·L-1; distilled water was used as the control. After treatment of seeds, lettuce showed an increase of up to 75.50% in its rate of germination, while for corn, seed stimulation occurred at 0.25 g·L-1 of rhamnolipids. Regarding to soybeans, biosurfactants did not influence germination, however favored seedling development. The tensioative increased both the germination and development of sunflower seeds.
