Ozone dose (g.kg^-1 O₃)
	Control	0.47	0.73	0.79	1.1	1.2	1.41
Batch # 1	8	4	-	4	4	-	4
Batch # 2	8	-	5	4	4	-	4
Batch # 3	8	-	4	4	4	4	-
Batch # 4	8	4	4	4		4	-
Batch # 5	8	-	-	-	5	5	5

Note: The experimental design consisted of five batches of 23 to 25 pots each, including eight control pots and four of the six doses for batches 1 to 4 and three of the doses for batch 5.
