From: Distinctive physiological and molecular responses to cold stress among cold-tolerant and cold-sensitive Pinus halepensis seed sources

Fig. 5

Polar or charged amino acids content of cold-sensitive and cold-tolerant P. halepensis seed sources. Arginine (Arg) (a), asparagine (Asn) (b), threonine (Thr) (c), lysine/glutamine (Lys) (d), glutamic acid (Glu) (e) and aspartic acid (Asp) (f) were determined 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
