A coupled photosynthesis–stomatal conductance model was parameterized and tested with branches of black spruce ( Picea mariana  (Mill.) B.S.P.) and jack pine ( Pinus banksiana  Lamb.) trees growing in the Northern Study Area of the Boreal Ecosystem–Atmosphere Study (BOREAS) in Manitoba, Canada. Branch samples containing foliage of all age-classes were harvested from a lowland old black spruce (OBS) and an old jack pine (OJP) stand and the responses of photosynthesis ( A  n ) and stomatal conductance ( g  s ) to temperature, CO 2 , light, and leaf-to-air vapor pressure difference (VPD) were determined under controlled laboratory conditions at the beginning, middle, and end of the growing season (Intensive Field Campaigns (IFC) 1, 2, and 3, respectively). The parameterized model was then tested against  in situ  field gas-exchange measurements in a young jack pine (YJP) and an upland black spruce (UBS) stand as well as in the OBS and OJP stands.
