Other claims from this paper (11)
- Intervention effect Thinning improved the apple canopy radiation environment.
- Observation The invalid canopy space in thinned apple orchards approached zero.
- Observation Minimum mean relative PAR in unthinned apple orchards was 17%.
- Observation Space below 0.3 relative canopy height in unthinned apple orchards was invalid.
- Intervention effect Thinned orchards had improved apple leaf photosynthetic efficiency.
- Intervention effect Thinning increased apple photosynthetic rate by 7.8% at the middle canopy.
- Intervention effect Thinning increased apple photosynthetic rate by 10.2% at the canopy bottom.
- Intervention effect Apple maximum carboxylation and electron transfer rates rose in thinned orchards.
- Association Apple leaf photosynthetic potential was significantly correlated with leaf nitrogen concentration.
- Association Apple leaf nitrogen concentration was strongly correlated with relative PAR.
- Method / resource Relative apple leaf nitrogen distribution could estimate leaf photosynthetic potential and relative PAR.
