The Relationship of Leaf Area and Foliage Biomass to Sapwood Conducting Area in Four Subalpine Forest Tree Species
Year: 1981
Type: article
Abstract: Leaf dry weight and area were strongly correlated with sapwood area measured at 1.37 m, but leaf area per unit sapwood area varied widely among species: 1.88 m²·cm-2 for subalpine fir, 0.72 for Engelmann spruce, 0.44 for lodgepole pine, and 0.19 for aspen. The leaf area: sapwood area relationship was nearly constant for different portions of the crown, although the relationship was erratic in subalpine fir. Thus the upper portion of a larger tree has the same leaf area: sapwood area ratio as the entire crown of a smaller tree. This supports the hypothesis that a physiological balance exists between conducting tissue and the water requirements of the shoot. Forest Sci. 27:477-482.
