N2  - Net CO2 exchange was investigated at several photon flux densities and day temperatures in both 21% and 2% O2. Light saturation occurred between 400 and 500 µEm-2, s-1 in attached, fully expanded leaves of peppermint. Maximum rates of 'apparent' photosynthesis occurred at 20&#176;C. The important determinants of 'apparent' photosynthesis were an increase in 'true' photosynthesis when temperature was increased to 25&#176;C, a steady increase in dark respiration with increased temperature and a rapid increase in photorespiration between 15 and 30&#176;C. Such net CO2 exchange characteristics of peppermint support the photosynthate model proposed to explain environmental effects on oil composition.
