Other claims from this paper (8)
- Intervention effect Continuous light at 40 μmol; m −2 S −1 induced maximal expansion on intact and excised plants.
- Intervention effect Lower light intensities had only a partial effect on leaf expansion.
- Association Growth rate over the first 24 hours rose linearly with light intensity up to 130 μmol; m −2 S −1.
- Observation An intensity of 130 μmol; m −2 S −1 was supra optimal for final leaf size.
- Observation Full leaf expansion required about 15 mol photons m −2.
- Observation Light application mode, intensity and duration were not critical after the energy requirement was met.
- Intervention effect With insufficient total light, interrupted irradiance increased leaf elongation efficiency.
- Intervention effect With insufficient total light, longer low intensity application increased leaf elongation efficiency.
