Fig. 2

Photosynthetic pigments and soluble sugars content of cold-sensitive and cold-tolerant P. halepensis seed sources. Chlorophyll a (Chl a) (a), chlorophyll b (Chl b) (b), carotenoid (Car) (c), glucose (d), fructose (e) and sucrose (f) were determined for plants under control (white bars) and cold-stress (black bars) conditions. 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
