抄録	Atmospheric nitrogen deposition and [CO2] are increasing and represent environmental problems. Planting fast-growing species is prospering to moderate these environmental impacts by fixing CO2. Therefore, we examined the responses of growth, photosynthesis, and defense chemical in leaves of Eucalyptus urophylla (U) and the hybrid of E. deglupta x E. camadulensis (H) to different CO2 and nitrogen levels. High nitrogen load significantly increased plant growth, leaf N, photosynthetic rate (A_[growth]), and photosynthetic water use efficiency (WUE). High CO2 significantly increased A_[growth], photosynthetic nitrogen use efficiency (PNUE) and WUE. Secondary metabolite (SM, i.e. total phenolics and condensed tannin) was specifically altered; as SM of U increased by high N load but not by elevated [CO2], and vice versa for SM of H.
