Other claims from this paper (12)
- Association Leaf area index was only weakly associated with canopy transmittance.
- Mechanism Higher leaf area index corresponded to more foliage aggregation and lower light-interception efficiency.
- Association Shorter mean petiole length was associated with greater leaf aggregation.
- Association Shorter mean petiole length was associated with lower light-harvesting efficiency.
- Association Leaf size was not associated with light-harvesting efficiency in the reported comparison.
- Association Clones with longer petioles invested more biomass in petioles.
- Association Petiole length was negatively related to leaf area index.
- Association Upper-canopy leaves were larger than lower-canopy leaves.
- Association Upper-canopy leaves had greater dry mass and nitrogen per unit area than lower-canopy leaves.
- Association Canopy plasticity in dry mass and nitrogen per area was greater in clones with greater midrib biomass investment.
- Association Canopy plasticity in dry mass and nitrogen per area was lower in clones with relatively longer petioles.
- Mechanism The authors infer a trade-off between photosynthetic plasticity and support biomass investment.
