To determine the effects of environmental factors on the radial growth of mature trees in a natural
stand, ring-width series (1887 to 1987) in canopy trees growing in warm-temperate forest of the Mie
university was investigated.
(1) The mean ring-width series, calculated on cores from 76 canopy coniferous trees (Abies firma
Sieb. et Zucc.: 29, Cryptopmeria japonica D. Don: 6, Tsuga sieboldii: 41) showed stagnant radial
growth (1896 to 1906, 1913 to 1929) and successive increase in radial growth after 1945. The
reasons for these fluctuations in radial growth could not be determined for lack of long term
meteorogical records on the university forest.
(2) Spectrum analysis on the mean ring-width series indicated periodicity in radial growth, the periods
being 2.2, 3.3, 10-11.5, 22.2, 90.9 years and so on.
(3) Some of these periods could be found in an annual mean temperature series and annual precipitation series, these being the longest nearby meteorogical records (Nagoya meteorogical observatory).
The university forest is apart 110 km or more from the meteorogical observatory, and thus the
coincidence of these periods indicates to possibly be due not to microclimatic causes but global
scale climatic variation.
