Table 3 Main characteristics of the trees studied (defoliation class (defoliated and non-defoliated), diameter at breast height, height (h), basal area (Ab), sapwood area (As), maximum leaf area (AL), leaf-to-sapwood area ratio (AL:AS))
From: Below-ground hydraulic constraints during drought-induced decline in Scots pine
