Key message Ozone-induced reduction in the whole-plant dry mass of high-fertilisedFagus crenataseedlings was offset by the increase in leaf area, although the exposure to ozone decreased net photosynthetic rate. Abstract To clarify the effects of ozone (O3) on the growth of Fagus crenata seedlings under different soil nutrient conditions, seedlings were grown for two growing seasons under nine treatments...
Key MessageElevated CO2concentration affected biomass partitioning in above-ground biomass, but size and number of water-conducting cells were unchanged inLarix kaempferi, Kalopanax septemlobusandBetula platyphylla...
Key messageElevated CO2reduced fine root dynamics (production and turnover) of white birch seedlings, especially grown in volcanic ash soil compared with brown forest soil. Abstract Increased atmospheric CO2 usually enhances photosynthetic ability and growth of trees. To understand how increased CO2 affects...
Key messageThe CO2effect on the root production of a broad-leaved community was insignificant when grown in brown forest soil, however, it was positively large when grown in volcanic ash soil. Abstract We evaluated the root response to elevated CO2 fumigation of 3 birches (Betula sp.) and 1 deciduous oak...
Key messageElevated CO2enhances the photosynthesis and growth of hybrid larch F1seedlings. However, elevated CO2-induced change of tree shape may have risk to the other environmental stresses. Abstract The hybrid larch F1 (Larix gmelinii var. japonica × L. kaempferi) is one of the most promising species for timber production as well as absorption of atmospheric CO2. To assess the...
We examined the growth and photosynthetic responses of Japanese forest tree species to sulfur dioxide (SO2) under different nitrogen (N) loads to soil. We grew Quercus serrata, Fagus crenata, Castanopsis sieboldii, Larix kaempferi, Pinus densiflora, and Cryptomeria japonica seedlings in Andisol supplemented with N as NH4NO3 solution at 0, 20, and 50 kg ha−1 year−1. Seedlings were exposed daily to...
To clarify the effects of ozone (O3) on nitrogen (N) metabolism in the leaves of Fagus crenata seedlings under different N loads, the combined effects of O3 and N load on N enzyme activity, amino acid profiles and soluble protein concentrations were investigated. The seedlings were grown in potted andisol supplied with N at 0 (N0), 20 (N20) and 50 kg ha−1 year−1 (N50) and were exposed to charcoal-filtered...
To obtain the basic data for evaluating the critical level of ozone (O3) to protect Japanese deciduous broad-leaved forest tree species, the growth and photosynthetic responses of Fagus crenata seedlings to O3 under different nitrogen (N) loads were investigated. The seedlings were grown in potted andisol supplied with N as NH4NO3 solution at 0, 20 or 50 kg ha−1 year−1 and were exposed to charcoal-filtered...
The objectives of this study were to clarify the influences of nitrogen (N) load on the growth and photosynthetic responses of Quercus serrata seedlings to O3 and to obtain basic data for evaluating the critical levels of O3 for protecting Q. serrata forests in Japan. The effects of O3 and/or N load on growth and photosynthetic activity of Q. serrata seedlings were investigated during the two growing...
We examined the carry-over effects of ozone (O3) and/or water stress on leaf phenological characteristics and bud frost hardiness of Fagus crenata seedlings. Three-year-old seedlings were exposed to charcoal-filtered air or 60nll1 O3, 7h a day, from May to October 1999 in naturally-lit growth chambers. Half of the seedlings in each gas treatment received 250ml of water at 3-day intervals (well-watered...
