Abstract
s, like other organisms, have phases of youth, maturity and senescence, each stage being marked by changes within ,the stem. Mature timber has become scarce with the depletion of the world's natural forests, and in many countries the wood-using industries are having ,to rely ,increasingly on second growth stands or on planted softwoods. A high proportion of plantation produce is in the form of thinning or tops, small stems with juvenile timber characterized by below average cell length, low density and abnormal longitudinal shrinkage.
