The wood anatomy of Scots pine sapwood can influence its treatability. A microscopic analysis on the wood material from four different stands in Northern Europe was performed using tangential sections from the outer part of Scots pine sapwood. Single correlations of the ray composition and lignification state of the ray parenchyma showed the influence of these factors on radial penetration depth and the ratio of filling. Early lignification was negatively correlated with radial penetration depth and ratio of filling. The study shows that ray composition and lignification of ray parenchyma cells are important contributors to fluid flow in radial direction.
