Other claims from this paper (10)
- Observation Lettuce seeds still responded to light when moisture exceeded 6%.
- Intervention effect Mannitol immersion lessened seed responsiveness to irradiation.
- Intervention effect Sucrose immersion lessened seed responsiveness to irradiation.
- Intervention effect PEG 400 at 0.03 molarity reduced germination by about 50%.
- Intervention effect Mannitol at 0.07 M brought about about 50% reduction in germination.
- Intervention effect Sucrose at 0.05 M brought about about 50% reduction in germination.
- Intervention effect Red light overcame the additional germination effect of 0.1 M mannitol at 30°C.
- Intervention effect Red light overcame the additional effect of 0.025 M PEG 400 at 30°C.
- Intervention effect Red light did not overcome the effect of 0.1 M sucrose.
- Intervention effect Gibberellic acid had no effect on treated lettuce seeds.
