Physiological quality of Urochloa brizantha seeds submitted to priming with calcium salts

, 2019
Seed priming provides a variety of benefits, including seed invigoration and reduced dormancy. Urochloa brizantha seeds are typically primed with difficult-to-acquire potassium nitrate (KNO3). In this sense, calcium salts stand out as an alternative, but
