Table A2.

Analysis of variance (ANOVA) of physiological parameters. The displayed results are p-values for individual factors (time, cultivar, drought and ozone) and their multiple interactions. Values in bold are significant at α = 0.05. SDW, shoot dry weight; g_s, stomatal conductance; RWC, relative water content; Φ_PSII, actual quantum yield of PSII; F_v/F_m, maximum quantum yield of PSII.
