- Abstract
Branches of nine-year-old loblolly pine trees grown in a 2 × 2 factorial combination of fertilization and irrigation were exposed for 11 months to ambient, ambient + 175, or ambient + 350 μmol mol−1 CO2. Rates of light-saturated net photosynthesis (Amax), maximum stomatal conductance to water vapor (gmax), and foliar nitrogen concentration (% dry mass) were assessed monthly from April 1993 until September 1993 on 1992 foliage (one-year-old) and from July 1993 to March 1994 on 1993 foliage (current-year).
