Fig. 4

Response to exogenous glycine betaine (GB) and salicylic acid (SA) treatments under salt stress of (a) chlorophyll a (chlp a), b chlorophyll b (chlp b), and c carotenoid (crtn) content. CK = Control; GB2.5 = 2.5 mM GB; GB5.0 = 5.0 mM GB; GB7.5 = 7.5 mM GB; SA1.0 = 1.0 mM SA; SA1.5 = 1.5 mM SA; SA2.0 = 2.0 mM SA; and ST = saline treatment (150 mM NaCl). All data are mean ± standard deviation. Differences between treatments having different letters above the error bars are significant at P < 0.05
