| Research Abstract |
With use of open top chambers, the diameter growth of hybrid larch F1 (Larix gmelinii x L. kaempfrei) was suppressed by high O3 (60 ppb, 7 hours in day) which is mainly due to decrease of dry-mass needles and fine roots. At high CO2 (600 ppm, day), the growth of F1 and its parents was increased and the O3-induced depression was moderated. However, recovery of O3-induced decrease of F1 was not simply explained by stomatal closores by high CO2. Relative growth rate of young beech (Fagus crenata) trees was about 25 % suppressed by 60 ppb with free-air O3 fumigation, by contract no decrease in the same age of oak (Quercus mongolica var. crispula) trees was found.
