a Leaf area/sapwood area (in per square meter per centimeter) and b specific conductivity (k s) and c leaf-specific conductivity (LSC) by vertical position in the tree for old-growth and mature ponderosa pine (each point shows mean ± s.e. for n = 6 samples). The March harvest was before current year’s growth had started, and the September harvest was near the end of current year’s growth
