Other claims from this paper (12)
- Observation Photosynthetic and leaf traits differed significantly across canopy positions and planting densities.
- Association Instantaneous photosynthetic rate, transpiration rate and stomatal conductance decreased toward lower canopy layers.
- Association Intercellular CO2 concentration increased toward lower canopy layers.
- Association Water use efficiency first increased then decreased down the canopy at D3 density.
- Association Leaf length decreased down the canopy.
- Association Leaf width, area and water content increased down the canopy.
- Association Leaf traits were positively correlated with Ci.
- Association Poplar photosynthetic capacity increased as planting density decreased.
- Observation All D3 canopy layers performed efficient photosynthesis.
- Observation All living D3 canopy branches were functional.
- Observation Canopy layers 1 to 4 photosynthesized effectively at D1 and D2 density.
- Observation The fifth canopy layer had relatively weak photosynthetic capacity at D1 and D2.
