Bordered pit structure and function determine spatial patterns of air-seeding thresholds in xylem of Doulglas-fir (Pseudotsuga menziesii; Pinaceae) trees

Domec, Jean-Christophe, Lachenbruch, Barbara, and Meinzer, Frederick C.

Abstract:

The air‐seeding hypothesis predicts that xylem embolism resistance is linked directly to bordered pit functioning. We tested this prediction in trunks, roots, and branches at different vertical and radial locations in young and old trees of Pseudotsuga menziesii. Dimensions of bordered pits were measured from light and scanning electron micrographs,...
