Description:

Response of net photosynthetic rate (PN), stomatal conductance (gs), intercellular CO2 concentration (ci), and photosynthetic efficiency (Fv/Fm) of photosystem 2 (PS2) was assessed in Eucalyptus cladocalyx grown for long duration at 800 (C800) or 380 (C380) µmol mol-1 CO2 concentration under sufficient water supply or under water stress. The well-watered plants at C800 showed a 2.2 fold enhancement of PN without any change in gs. Under both C800 and C380, water stress decreased PN and gs significantly without any substantial reduction of ci, suggesting that both stomatal and non-stomatal factors regulated PN. However, the photosynthetic efficiency of PS2 was not altered.
