Stomatal conductance (g_s) of the flag leaf wheat at low (a,c,e) and high (b,d,f) O₃ concentrations and three irrigation regimes between 29 June (only measured at low O₃) and 31 July at four different times of the day. The treatments were applied for the period 26 June–23 July 2018, with high O₃ exposure starting on 28 June. Data for 29 June were not included in the statistical analysis as they were only obtained for low O₃. WW = well-watered (a,b); FD = frequent deficit irrigation (c,d); ID = infrequent deficit irrigation (e,f), with low volume applied on the day before 29 June, 3 July, and 24 July; 30 = peak O₃ concentration of 30 ppb; 80 = peak O₃ concentration of 80 ppb. Values are averages (± SE; n = 4).
