“…2; Table 3). Physiological activities are generally higher in fertile conditions than infertile ones (Tamm 1991;Koike 1995;Yazaki et al 2001;Eguchi et al 2004). Our results to the contrary could be due to the physical properties of the soil rather than its nutrient characteristics.…”

Though birch and alder are the common pioneer tree species which dominate in northeast Asia, little is known about the effects of the predicted increase in atmospheric CO 2 concentrations ([CO 2 ]) upon their photosynthesis in field conditions. To investigate this, we grew 2-year-old saplings of three Betulaceae species (Betula platyphylla var. japonica Hara, Betula maximowicziana Regel, and Alnus hirsuta Turcz) for 2 years in a free air CO 2 enrichment system in northern Japan. Since the effect of high [CO 2 ] is known to depend on soil conditions, we evaluated the responses in two soils which are widely distributed in northern Japan: infertile and immature volcanic ash (VA) soil, and fertile brown forest (BF) soil. For B. platyphylla, photosynthetic down-regulation occurred in both soils, but for B. maximowicziana, down-regulation occurred only in VA soil. The explanation is reduced nitrogen and Rubisco content in the leaf. For A. hirsuta, down-regulation occurred only in BF soil because of the accumulation of starch in foliage, which restricts CO 2 diffusion inside the chloroplast. The higher photosynthetic rate of A. hirsuta in infertile VA soil could be due to the sink for photosynthates in the N 2 -fixing symbiont. These three species are all able to down-regulate at high [CO 2 ]. However, it is possible that A. hirsuta would dominate in VA soil and B. maximowicziana in BF soil in the early stages of forest succession in a CO 2 -enhanced world.

“…The effects of [CO 2 ] on the wood of forest trees and with nitrogen acting in combination have been investigated (e.g., Hättenschwiler et al 1996;Yazaki et al 2001;Kostiainen et al 2004). Elevated [CO 2 ] and N-fertilization altered the dimensions of xylem vessels and wood fibers in a genotypespecific manner in three species of Populus (Luo et al 2005).…”

“…We studied oak and alder seedlings under strictly controlled conditions in a phytotron, because young seedlings are most responsive to [CO 2 ] (Saxe et al 1998;Medlyn et al 2001) and may be indicators of wood quality in mature trees (Yazaki et al 2001). Oak, a ring-porous tree lacking the ability for N 2 fixation, was expected to be more sensitive to nutrient limitations and show more severe changes in wood structure than alder, a diffuse-porous tree and N 2 fixer.…”

Wood structure might be altered through the physiological responses to atmospheric carbon dioxide concentration ([CO 2 ]) and nitrogen (N) deposition. We investigated growth, water relations and wood structure of 1-year-old seedlings of two deciduous broad-leaved tree species, Quercus mongolica (oak, a ring-porous species) and Alnus hirsuta (alder, a diffuse-porous species and N 2 -fixer), grown under a factorial combination of two levels of [CO 2 ] (36 and 72 Pa) and nitrogen supply (N; low and high) for 141 days in phytotron chambers. In oak, there was no significant effect of [CO 2 ] on wood structure, although elevated [CO 2 ] tended to decrease stomatal conductance (g s ) and increased water use efficiency regardless of the N treatment. However, high N supply increased root biomass and induced wider earlywood and larger vessels in the secondary xylem in stems, leading to increased hydraulic conductance. In alder, there was significant interactive effect of [CO 2 ] and N on vessel density, and high N supply increased the mean vessel area. Our results suggest that wood structures related to water transport were not markedly altered, although elevated [CO 2 ] induced changes in physiological parameters such as g s and biomass allocation, and that N fertilization had more pronounced effects on non-N 2 -fixing oak than on N 2 -fixing alder.

“…Stem expansion could indicate that elevated CO 2 affects the apical meristem and cambium differently or has different effects on cell division and cell expansion, or both. Elevated CO 2 may affect plant development not only by altering photosynthetic activity, but also by altering apical cell development (Yazaki et al 2001).…”
