Simulation of 1-year-old Populus tremuloides response to ozone stress at Ithaca, USA, and Suwon, Republic of Korea

摘要

The growth of 1-year-old aspen was simulated using TREGRO, a computer simulation model of individual tree growth, to assess potential effects of ozone (O_3). TREGRO was parameterized using information from a field experiment conducted at Ithaca, NY, USA; the model was then applied using environmental information from Suwon, Korea, where O_3 exposures of sapen had Not been conducted. In the parameterization at Ithaca, the simulated and measured total biomass differed by about 3/100 and the Differences between measured and simulated biomass gain of leaf, shoot, and root were 15.4, 8.3, and 4.4/100, respectively.
