Stimulation of PGP bacteria on the development of seeds, plants and cuttings of the obligate halophyte Athrocaluon(Arthrocnemum) macrostachyum(Moric.). soil bacteria for incresing Artrocaulon machostachyum growth

we tested the effect of five PGP bacteria and other endophytic bacteria on seed germination and plant growth (with and without salt in the medium) and cuttings growth (in a medium without salt) of A. macrostachyum. It is highlighted the growth promotion in this strict halophyte due to the presence of PGP bacteria and no salt needed.Thus, in a medium without salt, the bacterial strains Kocuria polaris Hv16, Arthrobacter siccitolerans C58 and Rahnella aceris RTE9 enhanced the develop both stems and roots more than 60 %.Furthermore, the germination was encouraged more than 30% by the presence of both the Rahnella aceris RTE9 and Kocuria polaris Hv16 at 171 mM NaCl, the latter also had a biocontrol effect on the fungi that grew on the seeds.And for the first time, cuttings of this perennial specie were obtained and thanks to the inoculation with Kocuriapolaris Hv16 andArthrobacter siccitolerans C58 their root biomass were improved. Finally,our study demonstrates the potential of PGPs for optimizing the development of halophytes, either for environmental or agronomic purposes
