摘要
There is a positive correlation between the percentage of compression wood and specific gravity in Pinus wallichiana. Where compression wood is present a definite increase in specific gravity occurs in an annual ring, but the influence of compression wood on specific gravity is only local. The first-formed earlywood portion of the ring is the most suitable sampling point for a comparison of specific gravity between rings of the same or different trees. © 1978 Springer-Verlag.
