Fig. 8From: Identification of distinctive physiological and molecular responses to salt stress among tolerant and sensitive cultivars of broccoli (Brassica oleracea var. Italica)Concentration of primary metabolites altered by salt stress. Myoinositol (A); hydroxyproline (B); γ-aminobutyric acid (GABA) (C); galactinol (D); gluconic acid lactone (E) and gluconic acid (F) concentrations of salt-sensitive and salt-tolerant cultivars under control (white bars) or stressed (black bars) treatments. The units are the area of the peak per mg of sample. Data with different letter differ significantly (p<0,05), as determined by Duncan’s MRT test (n=4). Scale bars are mean + SEBack to article page
