Zhou et al. (2011)

Photosynthesis of eight-year-old saplings transplanted into open-top chambers and grown for an additional nine years at different atmospheric CO2 concentrations, with measurements of current-year needles of non-shaded top shoots being made on clear days between 0830 and 1130 hours in the last two years of the study
