AB The Earth is undergoing alterations at a high speed, which causes problems such asenvironmental pollution and difficulty in food production. This is where halophytes are interesting,due to their high potential in different fields, such as remediation of the environment and agriculture.For this reason, it is necessary to deepen the knowledge of the development of halophytes and howplant growth-promoting bacteria (PGP) can play a fundamental role in this process. Therefore, in thiswork were tested the effects of five PGP bacteria on its rhizosphere and other endophytic bacteriaat different concentrations of NaCl on seed germination, plant growth (0 and 171 mM) and cuttinggrowth (0 mM) of Arthrocaulon macrostachyum. The growth promotion in this strict halophyte ishighlighted due to the presence of PGP bacteria and the fact that no salt is needed. Thus, withoutsalt, the bacterial strains Kocuria polaris Hv16, Pseudarthrobacter psychrotolerans C58, and Rahnella acerisRTE9 enhanced the biomass production by more than 60% in both stems and roots. Furthermore,germination was encouraged by more than 30% in the presence of both R. aceris RTE9 and K. polarisHv16 at 171 mM NaCl; the latter also had a biocontrol effect on the fungi that grew on the seeds.Additionally, for the first time in cuttings of this perennial species, the root biomass was improvedthanks to the consortium of K. polaris Hv16 and P. psychrotolerans C58. Finally, this study demonstratesthe potential of PGPs for optimising the development of halophytes, either for environmental oragronomic purposes.
