Effects of the presence of 1 and 10 mm H₂O₂ in the incubation medium on electrolyte leakage in the presence and absence of 0.25 mm La³⁺. To facilitate H₂O₂ entry, before the experiment was started leaves were rapidly infiltrated with the same medium used in the treatment. Experimental conditions were as in Figure 2. Data are from one representative experiment out of four. ΔμS, Change in medium conductivity.
