Fig. 7From: 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 related to the Krebs cycle. Citric acid (A); succinic acid (B); malic acid (C); fumaric acid (D); aspartic acid (E) and glutamic 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
