Figure 6

Leaf photosynthesis under saturating light (Asat), stomatal conductance (gs) and transpiration (E) of Solanum lycopersicum seedlings grown under ambient temperature (A, C and E) and 7-d 42 °C heat wave treatments (B, D and F) as function of leaf water potential (Ψl) during the periods of drought stress and the following recovery. Data points are raw data of the measured variables. Data are fitted with exponential functions: y = a × e (-bx) (P <0.01 for all parameters). The correlation coefficients (R2) are also given. Red and open symbols represent values during the drought stress, while blue and closed symbols represent values during the recovery from drought. Treatments: AD–Ambient temperature plus drought; HD–Heat wave plus drought.
