Fig. 4From: Identification of distinctive physiological and molecular responses to salt stress among tolerant and sensitive cultivars of broccoli (Brassica oleracea var. Italica)Amino acids with similar accumulation patterns between stress sensitive and stress tolerant cultivars. Alanine (Ala) (A); phenylalanine (Phe) (B); valine (Val) (C); arginine (Arg) (D) and isoleucine (Ile) (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
