Other claims from this paper (12)
- Intervention effect Green pruning increases light-saturated CO2 assimilation.
- Observation Green pruning changes total leaf area and foliage distribution.
- Intervention effect The 50% pruning treatment reduced daily net biomass production by 20% immediately.
- Observation High light interception occurred at leaf area index 4.0.
- Intervention effect The 50% pruning treatment reduced leaf area index to 3.5.
- Observation Physiological responses compensated fully for lost intercepted radiation within 110 days after 50% pruning.
- Intervention effect The 70% pruning treatment reduced leaf area index to 1.9.
- Intervention effect The 70% pruning treatment reduced daily net biomass production by 77%.
- Association Increased assimilation after pruning raised modeled daily net biomass production by 20% in 50% pruned trees.
- Association Increased assimilation after pruning raised modeled daily net biomass production by 25% in 70% pruned trees.
- Association Changes in leaf area and foliage distribution increased daily net biomass production by 47% in 50% pruned trees.
- Mechanism Reduced photosynthetic potential following 70% pruning caused only small changes in leaf area and foliage distribution, with little effect on daily net biomass production.
