This work aimed to investigate the phytotoxic potential of the aerial and underground parts of Senna occidentalis and S.
obtusifolia on the germination and initial growth of lettuce and onion.
Four concentrations were used of each ethanol extract (0, 250, 500 and 1000 mg L-1), with four replications of 50 seeds.
From the investigated species, the aerial part of S.
occidentalis interfered in onion germination and the aerial part of S.
obtusifolia interfered in the germination...
