一般講演（ポスター発表） P1-P-441 （Poster presentation）
Exchanges of energy, materials and information between organisms and their environments are ecological processes, which are fundamentally metabolic. Therefore this study focuses on the ontogenetic change of whole-plant respiration from seeds to current-year seedlings of Fagus crenata Blume in a pot-experiment, which were collected from Mt. Gassan, Japan. We compared whole-plant respiratory traits of seedlings, including roots, grown in two different light environments, i.e. open (no shading) and shaded (70% shading). The results showed that different light environments generated a shift of energy and material allocation to above- and below-ground parts of individual seedlings. We will continue to observe the impact of the shading on the adaptability of individual current-year seedlings including roots.
The ontogenetic change of energy allocation of whole plants to above- and below-ground parts related with the balance between carbon-acquisition and water-uptake. The whole-plant physiological study provides an intelligible understanding about ecological adaptation of seedlings as terrestrial plants.
