DescriptionPitch pine seedlins were grown at constant temperature and photoperiod. Net CO2-uptake h-1 g-1 leaves decreased stadily during ontogeny until leaf production ceased. Thereafter, there was no change or a slight increase. Though the 0ntogeneic pattern was the same in populations native to different geographic areas, there were differences among populations in the rate of CO2-uptake. Root respiration, calculated from the difference between CO2-uptake and net assimilation rate, accounted for 6 to 69 per cent of diurnal assimilation.
