Other claims from this paper (9)
- Intervention effect Plants transferred to a given light intensity had a unit leaf rate almost identical to plants grown at that intensity.
- Association Field and cabinet observations show a similar relationship between specific leaf area and unit leaf rate in Impatiens parviflora.
- Observation Unit leaf rate of about 3.3 mg/cm2/week was reached at 26 cal/cm2/day in the cabinets and 51 cal/cm2/day in the field.
- Observation Efficiency of conversion of visible radiation was about 15% at the lowest light intensity in the cabinets.
- Observation Efficiency of conversion of visible radiation was about 3% in full daylight.
- Observation Adaptation to a new light climate was largely complete within a week.
- Mechanism Leaf growth of adapted and transferred plants is in harmony with the hypothesis that a balance between water-driven extension and cell wall thickening controls leaf expansion.
- Association The specific leaf area and unit leaf rate relationship accounts for the slight changes in relative growth rate with changing light at medium intensities.
- Observation Unit leaf rate curves for field and cabinet conditions are closely similar at very low light intensities and diverge at higher intensities.
