Salt Tolerance Strategies of Nitraria tangutorum Bobr. and Elaeagnus angustifolia Linn. Determine the Inoculation Effects of Microorganisms in Saline Soil Conditions

Increasing salinization threatens the normal growth of halophytes in saline habitats, especially at seedling stage. Soil beneficial microorganisms have potential to promote salt tolerance halophytes, but less attention has been paid various responses between different with microbial inoculations. Here we performed pot experiments assess Nitraria tangutorum Bobr. and Elaeagnus angustifolia Linn. arbuscular mycorrhizal fungi (AMF) plant growth-promoting rhizobacteria (PGPR) inoculation soil conditions. The results showed that neither a single AMF nor PGPR promoted N. tangutorum. In contrast, co-inoculation not only biomass accumulation also absorption P, K+, Ca2+ roots, N, Na+, leaves. Co-inoculation increased K+/Na+ ratio roots as well Ca2+/Na+ both leaves Na+ is an important inorganic osmolyte, essential for efficient osmoregulation alone could E. angustifolia. inoculation, solely or combined PGPR, was K+ N leaves, maintenance selective transportation from proline glycine betaine Increased nutrient absorption, ion homeostasis, AMF-inoculated helped reduce toxic effects damage caused by osmotic stress “Plant-microbe specificity” leads seedlings strategies osmoregulation, acquisition, determine differential E.angustifolia inoculations under
