Abstract
Hydration level of seeds determines vigour of soybean,Glycine max (L.) Merr. The seeds should contain at least 20% of moisture for a good performance at low temperatures. This hydration level can be reached by pre-sowing exposure of seeds in water saturated atmosphere (WSA). The exposure decreases both visible symptoms of chilling injury and leaching electrolytes during imbibition, and increases both germination and growth of seedlings at 10 to 12 °C. It is concluded that the cell membrane integrity is re-established in a course of the WSA exposure.
