Physiological measurements of cold-sensitive and cold-tolerant P. halepensis seed sources. Water potential, gas exchange and photosynthesis measurements of cold-sensitive and cold-tolerant P. halepensis seed sources under control (white bars) and cold-stress (black bars) conditions. Water potential (Ψw) (a), stomatal conductance (gs) (b), transpiration (e) (c), Net photosynthesis (Pn) (d), Maximal efficiency of PSII (e), quantum yield of non-cyclic electron transport (ΦPSII) (f) and instantaneous water use efficiency (WUEinst) (g). The letters above the bars marks the significant difference among the cold-stressed seed sources following the post hoc Duncan’s test. Scale bars are mean + SE, being the number of samples n = 5
