The potential for newly-germinated cabbage seed survival and storage at sub-zero temperatures
1988
Finch-Savage, W.E. | McQuistan, C.I.
The moisture content of newly germinated cabbage seed (radicles 1 ±0·5 mm long) was reduced to 14% of f.wt without loss of viability. As the moisture content was reduced below 45%, the temperature at which the germinated seeds froze, and therefore died, decreased progressively to a minimum of −34 °C at 19% moisture content. No freezing exotherms were recorded in seeds with moisture contents below 19%. Seeds with a moisture content between 14 and 16% maintained viability for at least 1 week when cooled at 2·6°C.min−1 to −20 °C and held at this temperature, indicating the potential for prolonged storage of these low-moisture-content germinated (LMCG) seeds.
