The values for chambers are mean values ±S— across the 4 positions; the positional values are means ±S— across the 9 chambers; the overall mean is the mean ±S— across and within chambers (36 points). 14 d with a solution of Peters 20-20-20 fertilizer. Plants were exposed to /xl/1 O3 for 2 h when they had one partially developed trifoliate leaf (14 d from seed, experiment 1) or two well- developed trifoliate leaves (21 d from seed, experiments 2 and 3). The three experimental designs were run to test the uniformity of plant response across and within chambers. In the first experiment, 1 plant was plac
