WHITE PINES OF EUROPE 105. ,io 210 300 AGE Figure 3. Adult height growth of European white pines in comparison with alpine Picea dbies: aZ...al3 = Pioea dbies (after Frauendorfer, 1954); <?I...<2III = Pinus oembra (after Figala, 1927); pI...pV = Pinus peuce (after Nedjalkov, 1963); sla...sVa = Pinus sibiriaa (after Leskov and Semeckin, 1963); pD = single data for Pinus peuce in Great Britain (after MacDonald et al. , 1957); PH = single-tree data for Pinus peuce in natural stands (after Mtlller, 1928). important is the long lasting, uniform growth of all three species; it results in good volume production in old and very old trees. The best trees at an age of 300 years may have a diameter of 100 cm and more (Jamnicky, 1964). A diameter of 60 cm at breast height is common in 200 to 250 years old P. sibirica (Hempel and Jung, 1968). Two-hundred- year-old P. cembra trees may reach 40 cm and more (Figala, 1927; Gregori 1887), and selected trees of Swiss stone pine in Austria reach the same dimensions as P. sibirica trees (Holzer, 1969). Similar dimensions may be found in P. peuce too (Nedjalkov, 1963). The crown form of these species in general is narrow with small branches except that in open stands--above timberline especially—very often we find individuals with heavy branches, multi-forked trunks, and sometimes with candelabrum branches or a spherical crown. Stems without defects are rare..
