The results of the germination test on lettuce seeds exposed
to DE and FE were similar, showing a germination reduction for
all concentrations; the 20 mg mL−1 had the lowest mean value
(DE = 12.83%; FE = 4.54%) compared to the negative control (100%).
With regard to the germination mean time and speed, the seeds
treated with DE and FE were significantly different compared to the
negative control. However, withregard to the DE and FE treatments,
only 5 mg mL−1 and 10 mg mL−1 did not differ between them. For
the mean speed, all treatments were significantly different for both
DE and EF.
