Fig. 3From: Identification of distinctive physiological and molecular responses to salt stress among tolerant and sensitive cultivars of broccoli (Brassica oleracea var. Italica)Amino acids with differential accumulation patterns between stress sensitive and stress tolerant cultivars. Proline (Pro) (A); histidine (His) (B); asparagine (Asn) (C); threonine (Thr) (D) and lysine (Lys) (E) concentrations of salt-sensitive and salt-tolerant cultivars under control (white bars) and stress (black bars) conditions. Data with different letters differ significantly (p < 0.05), as determined by Duncan’s MRT test (n = 3). Scale bars are mean + SEBack to article page
