%X <p>In laboratory studies the heartwood content seems to be the only natural property of a wood of different tree species influencing the decay resistance. Moistening and drying by diffusion happen quite slowly. Scots pine (<em>Pinus sylvestris</em> L.) sapwood takes moisture by capillary action quicker than pine heartwood and Norway spruce (<em>Picea abies</em> (L.) H. Karst.) wood. Swelling and shrinkage are also greatest in pine sapwood. Impregnation of pine sapwood can give it better hydrophobic and dimensional stability than that of pine heartwood.</p>
