Other claims from this paper (7)
- Observation Upper leaf maximum photosynthesis was about four times higher than lower leaf photosynthesis.
- Intervention effect Shaded upper leaves had about half the maximum photosynthesis of upper leaves.
- Association Night respiration related linearly to previous-day photosynthesis at a fixed temperature.
- Intervention effect Leaf area, nitrogen, chlorophyll and carboxylation measurements did not differ significantly with shading.
- Intervention effect Shading decreased electron transport and light use efficiency.
- Observation Respiration in shaded leaves was lower than expected from the sugar relationship.
- Observation Starch concentrations lacked a similar difference.
