Salinity stress mitigation on Zea mays L. seedling by halotolerant bacteria

Abstract Halotolerant bacteria are reported as a potential biostimulant to mitigate saline stress on various crops. The mechanism of halotolerant in elevating plant growth under is associated with their growth-promoting (PGP) traits. This study evaluated the activity single-strain phosphate-solubilizing and its consortia that were able fix nitrogen produce ACC deaminase alleviating salinity Zea mays seedlings vitro conditions. One single strain five bacterial isolates tested for seedling assay four levels (0, 60, 80, 100 mM). In showed B1 ( Vibrio alginolycticus ) all significantly increased root number at 60 mM level. Consortium B3 V. alginolyticus+Salinicola zeshunii was also improve fresh weight (by 63.3%). Moreover, inoculation consortium affected more proline soluble sugar accumulation Z. when compared uninoculated seedlings. We conclude application alginolyticus + S. potentially used improving slightly moderately areas.
