HERNANDEZ PERALES, Ma. Magdalena et al. Mitigating the effect of chloride salts and sulfáticas germination of Salicornia bigelovii (Torr.) by beneficial bacteria in vitro. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.4, pp.923-934. ISSN 2007-0934.

In Mexico 30% of its agricultural land is affected by salinity. This affects exposed to conventional agriculture based glycophyte not be profitable and productive. In the interest of expanding knowledge with halophytes of agroindustrial interest and to propose them to the productive sector presents problems of salts, this study under conditions of hydrochloric salinity and induced sulfate developed, evaluated two genotypes of Salicornia bigelovii in the stages of germination and development (improved genotype SOS-7 and wild genotype Bay Kino= BK=), developing in salinity conditions: two sodium chloride (NaCl) at 0.5 molar and 1 molar and two calcium sulfate (Ca2SO4+2H2O) to 0.5 Molar and 1 Molar, with inoculation of two plant growth promoting bacteria (PGPR) (Azospirillum halopraeferens= Ah and Klebsiella pneumoniae= Kp) and an uninoculated control. The results indicate that when evaluating Salicornia in saline conditions sulfate and hydrochloric inoculation with BPCV, including the results include a greater percentage of germination was observed in the presence of BPCV, excelling those inoculated with Kp. It was observed that as the salinity increases, Kp presents be more effective with wild genotype BK. Studies concerning as possible bio-fertilizers are needed in different phenological stages with genotypes studied, who for the germination stage, turned out to have expectations.
