Climate of origin shapes variations in wood anatomical properties of 17 Picea species.

Most of the 17 spruce species had a ground diameter of approximately 2 cm, still, the differences among species were highly significant ( P < 0.0001), and the basal diameters ( BD 6 ) of P. meyeri and P. schrenkiana were relatively small, showing poor environmental adaptability (Fig. 3 B).
