Volume growth of an average Pinus arrnandii in a natural stand on Mt. Alishan, Taiwan. Drawn from data provided by Mr. Jih-Ching Liao, Assistant Professor of Dendrology, Taiwan University, Taipei, Taiwan. The growth performance under introduction is not known,but there is a report (Dallimore and Jackson, 1923) that it grows rapidly at Kew in light, well-drained loam under similar conditions to P. exoelsa Wallich (Syn. P. wallichiana Jacks.). Trees 20 years old cone freely and some of the seeds are fertile. Two planted stocks of P. arrnandii at the Asakawa Experimental Forest in Tokyo, Japan, are not so healthy (Fig. 26). TIMBER QUALITY P. arrnandii is characterized by pale, yellowish-white sapwood and yellowish-brown heartwood which is clearly distinguishable from the sapwood. It is straight-grained and medium- to fine-textured. Growth rings are distinct, wide, and uniform in width (Fig. 27). Transition from springwood to summerwood is abrupt and delineated by a broad band of darker summer wood. Wood rays are very fine and not visible to the naked eye. Under a hand lens they appear to be whitish or brownish and contain a horizontal resin duct, forming a fine, close fleck on the quarter Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original North Atlantic Treaty Organization; International Union of Forestry Research Organizations; United States.
