In this paper the authors point out the impact of ultrasounds on seed germination in bird’s-foot trefoil (Lotus corniculatus L.). The bird’s-foot trefoil seeds, grouped into 4 size groups, were exposed to ultrasounds with variable intensities and exposure times ranging between 0.11 and 2.72 W/cm2 and between 10 and 160 seconds. Research shows that both germinating energy and germinating ability measured at 10 and 21 days, respectively, were positively impacted by ultrasounds. The highest values were when we treated with ultrasounds medium- and large-size bird’s-foot trefoil seeds.
