Other claims from this paper (8)
- Association Blue irradiation sharply lowered hypocotyl growth rate while resonance frequency rose slightly.
- Association Blue irradiation sharply lowered hypocotyl growth rate while resonance frequency rose slightly in sunflower.
- Association Light dose did not influence lag-time or half-time of blue-light inhibition.
- Association Light dose strongly affected the amount of inhibition.
- Intervention effect A temperature fall from 30 to 20 degrees Celsius lengthened the blue-light response lag-time.
- Observation Cucumber hypocotyl length and blue-light inhibition had the same half-time, 15 to 25 seconds.
- Observation Sunflower hypocotyl length and blue-light inhibition had the same half-time, 90 to 150 seconds.
- Mechanism The authors infer that blue light immediately decreases cell-wall yielding after a fixed lag, then growth slows as turgor reaches a new steady state.
