Abstract
A laboratory experiment was conducted to determine the effect of the hydrophilic polymer Waterlock B100 on the imbibition, respiration, and germination of seeds of the sweet corn (Zea mays L. var. saccharum) hybrid ‘Mevak’ at soil water matric potentials of -0.01, -0.40, -1.0, and - 1.5 MPa. Coated seeds had a higher final percentage of imbibition, higher rates of respiration, and germination at -0.01 and -0.40 MPa than uncoated seeds, but as the water potential decreased, the seed coating had a deleterious effect on the physiological processes leading to germination.Keywords
