Other claims from this paper (7)
- Association Leaf dry weight and leaf area were strongly correlated with sapwood area measured at 1.37 m.
- Observation Leaf area per unit sapwood area was 1.88 m²·cm-2 in subalpine fir.
- Observation Leaf area per unit sapwood area was 0.72 in Engelmann spruce.
- Observation Leaf area per unit sapwood area was 0.44 in lodgepole pine.
- Observation Leaf area per unit sapwood area was 0.19 in aspen.
- Association The leaf area to sapwood area relationship was nearly constant for different portions of the crown.
- Mechanism The results support the hypothesis of a physiological balance between conducting tissue and the water requirements of the shoot.
