Abstract:Lead as PbCl2 in solution was applied to the soil resulting in concentrations of 0, 20, 40, 80, 160, and 320 ppm. No effect on photosynthesis and transpiration, as studied by infrared gas analysis, was evident below tissue concentrations of 60 ppm lead in loblolly pine and 72 ppm lead in autumn olive. At these concentrations, photosynthesis was reduced 11 percent and 17 percent respectively and transpiration declined steadily. Forest Sci. 21:33-35.
