Effect of seed-priming with potassium (K) sources (K-nano-chelate, KNC, and sulfate (0, 2 and 4 %)) under drought stress (DS) conditions (0, -0.3, -0.6, -0.9, -1.2 and -1.5 MPa water potential) on the corn seedling traits was studied. Drought stress decreased the germination indices and seedling vigor. The highest germination, seminal root fresh and dry mass (RFM and RDM) was obtained in KNC primed seeds at -0.3 MPa DS. Mean germination time increased under DS conditions mainly in non-primeddoi:10.14720/aas.2016.107.1.12 fatcat:m7rpfgqezfcffdtfn6oqk6lwfa
