The Effect of Heat Shock on Seed Dormancy Release and Germination in Two Rare and Endangered L. Species (Fabaceae).

Many species exhibit seeds with physical dormancy (PY), but little is known about the ecological context of this dormancy. We focused on and , two threatened Sardinian endemic species inside the subgenus Bunge. Fresh seeds collected from the only two respective known populations were used to investigate the effect of mechanical scarification, heat shock, and water imbibition processes on PY release and germination.
