Christina W. Vertucci PLANT PHYSIOLOGY 1989. doi:10.1104/pp.90.4.1478
Other claims from this paper (10)
- Intervention effect Rapid cooling was optimal for seed vigor at freezable-water moisture levels.
- Intervention effect Cooling rate appeared to have no effect on seedling vigor at intermediate moisture.
- Intervention effect Cooling rate had no effect on very dry pea seeds.
- Intervention effect Rapid cooling markedly harmed germination of very dry soybean seeds.
- Intervention effect Rapid cooling markedly harmed germination of very dry sunflower seeds.
- Observation Glass transitions were observed at all moisture contents in rapidly cooled sunflower cotyledons.
- Observation Glass transitions were observed at all moisture contents in rapidly cooled soybean cotyledons.
- Observation Glasses were detectable in pea cotyledons at high moisture after rapid cooling.
- Mechanism At high moisture, aqueous and possibly lipid phase glasses were suggested to benefit seed survival at low temperature.
- Association At low moisture, lipid phase glass formation was associated with reduced seed viability.
