Sugarbeet (Beta vulgaris L.) seeds soaked in 50 times their weight of water for ½ to 8 days and air dried had faster rates of germination than washed or control seeds in laboratory tests at 38°C. Water temperatures of 15 or 25°C were superior to temperatures of 5 and 35°C during soaking treatment. The beneficial effects of soaking were retained in storage for at least 60 days after treatment. Soaking or washing treatments resulted in higher germination than control seeds at all concentrations of salt tested. Seeds soaked in fusicoccin germinated at a faster rate than seeds soaked in water. Under high temperature conditions in the field, soaking treatments increased the rate of emergence, but not total emergence.
