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.
Key words:
Biosurfactants, Pseudomonas aeruginosa LBI 2A1 and
