| Research Abstract |
Genetic analyses were done on the basis of composition and content of photosynthetic pigments, in connection with initial growth rates of planted seedlings, for Thujopsis lines selected from natural forests. Both growth rates and pigment contents differed among lines significantly. Growth rates were not correlated to contents of xanthophylls, but were to chlorophylls and carotenes; much higher correlation coefficients to alpha-carotene. Growth rates were closely related to specific leaf weight (SLW). The group of fast growing lines was specified throughout the two parameters of alpha-carotene and SLW. Growth responses of the lines were almost similar between in open and under-canopy planted-sites. Most of the lines showed higher growth rates in open site than in under-canopy site, but a part of lines higher growth rates in the under-canopy site.
