Investigating the effects of plant growth-promoting rhizobacteria isolates on germination and physiology status of durum wheat under salt stress

The aim of this work is to evaluate the seedling growth and physiology status wheat seeds inoculated with a suspension eight plant growth-promoting rhizobacteria (PGPR) isolates. For purpose, strains were isolated from roots native plants growing in Algerian steppe, then evaluated for their promotion (PGP) features, finally applied on seeds. obtained results showed that majority tested displayed pertinent PGP features. In vitro experiments, salinity affected negatively seed germination impaired while inoculation BC3, BC6 BC7 induced good rate improved significantly root length. greenhouse experience, data demonstrated non-inoculated accumulated significant amount osmoregulators (proline glycine betaine), recorded decrease chlorophyll content, compared plants, where tolerance latter has been much better high as well low osmolyte contents. may be useful extension our knowledge interaction between PGPR, view possible applications biofertilizer improve salinity-impacted regions.
