In the second in vitro experiment, the effects of inoculation with two rhizobial strains on growth, physiological, and biochemical responses of A. seyal seedlings was evaluated at four levels (0, 85, 171, and 256 mM) of NaCl. Results showed that at 342 mM NaCl, germination rate of A. seyal seeds declined by 56% from the control value, while any germination was recorded for Acacia bivenosa and Acacia sclerosperma seeds at the same salt level. Salt stress gradually decreased the growth, the soluble protein and the leaf-chlorophyll contents of A. seyal seedlings. However, rhizobial inoculation limits these adverse effects of salt on physiological and metabolic processes responses. A. seyal exhibited a moderate halophytic behavior; nodulation was enhanced by moderate salt stress. specialized Acacia seyal biochemistry germination physiology salt stress 076 32 7 1122-1136 2009 0190-4167 https://www.documentation.ird.fr/hor/PAR00004143 10.1080/01904160902943155 0190-4167 https://www.documentation.ird.fr/hor/PAR00004143 IRD - Base Horizon / Pleins textes 2009-11-09 2017-08-23 PAR00004143 fre
