BaCl2 effect on 22Na uptake in low-nutrient plants. The green and blue curves denote low-nutrient plants with and without BaCl2, respectively. Dark shading indicates night times. Expt.1 Roots: a Radioactivity ratio. b Rate of change of the radioactivity ratio. Expt.2 Roots: c Radioactivity ratio. d Rate of change of the radioactivity ratio. Expt.1 Leaves: e Radioactivity ratio. f Rate of change of the radioactivity ratio. Expt.2 Leaves: g Radioactivity ratio. h Rate of change of the radioactivity ratio
