The effects of drought stress on the physiological parameters in the sensitive (right) and tolerant (left) thyme plants: (a) the leaf water potential (MPa); (b) water content (%); (c) shoot dry weight (g); (d) net photosynthetic rate (µmol m⁻² s⁻¹); (e) stomatal conductance (mmol m² s⁻¹). ^* p < 0.05 vs. day 0 of Droughted group; ^** p < 0.01 vs. day 0 of Droughted group, ^*** p < 0.001 vs. day 0 of Droughted group, ^## p < 0.01 vs. day 0 of Watered group; ^### p < 0.001 vs. day 0 of Watered group; ^& p < 0.05 Droughted vs. Watered group; ^&& p < 0.01 Droughted vs. Watered group; ^&&& p < 0.001 Droughted vs. Watered group. Data are expressed as the mean ± S.E.M. Two-way ANOVA followed by the Sidak’s multiple comparisons test was executed.
