Other claims from this paper (7)
- Intervention effect Increasing top-canopy light absorption by 25% augmented tomato canopy photosynthesis by 6% in winter.
- Intervention effect The same 25% top-canopy light increase reduced tomato canopy photosynthesis by 7% in summer.
- Observation Measured tomato leaf elevation angle, leaflet angle and leaflet arrangement were already optimal for light absorption and photosynthesis.
- Observation Leaf phyllotaxis had no effect on tomato light absorption or photosynthesis.
- Intervention effect Increasing tomato leaf length-to-width ratio by 1.5 increased light absorption and photosynthesis by 6–10%.
- Intervention effect Increasing tomato internode length from 7 to 12 cm increased light absorption and photosynthesis by 6–10%.
- Intervention effect A spacious tomato ideotype with long internodes and long, narrow leaves increased crop photosynthesis by up to 10%.
