Rhizobacteria facilitate physiological and biochemical drought tolerance of Halimodendron halodendron (Pall.) Voss

Growth-promoting bacteria (GPB) have shown promising effects on serving plants against environmental constraints such as drought. Nevertheless, simultaneous of different GPB less been considered for arid land and under field conditions. We investigated the single combined application GPB, including free-living nitrogen-fixing (NFB), phosphate solubilizing (PSB), potassium (KSB), a combination NFB, PSB, KSB (NPK), control, at three drought stress treatments. In order to better understand interactions between we measured morphological, biochemical, physiological plant traits. The target was salt tree (Halimodendron Halodendron (Pall.) Voss), legume shrub native lands Central West Asia. All biofertilizer treatments enhanced growth, physiology, biochemistry seedlings, there were significant differences among PSB increased photosynthetic pigments, but treatment more efficient in transpiration rate stomatal regulation soluble carbohydrates. had highest effect root traits, taproot length, volume, cumulative ratio shoot. NFB diameter induced biomass translocation systems. However, only mixed (i.e., NPK treatment) most improve all morphological characteristics stress. Therefore, our results provided improvement some specific traits with biofertilizers increase growth establishment seedlings degraded lands.
